Definitions
- the present invention relates to a new radical polymerization process giving access to block polymers, as well as the block polymers thus obtained.
- Block polymers are usually prepared by ionic polymerization. This type of polymerization has the drawback of only allowing the polymerization of certain types of apolar monomers, in particular styrene and butadiene, and of requiring a particularly pure reaction medium and temperatures often below ambient so as to minimize the parasitic reactions, hence severe implementation constraints.
- Radical polymerization has the advantage of being easily carried out without excessive purity conditions being met and at temperatures equal to or above ambient. However, until recently there was no radical polymerization process allowing block polymers to be obtained.
- Controlled radical polymerization has the following distinctive aspects: 1. the number of chains is fixed throughout the duration of the reaction,
- the average molecular weight is controlled by the monomer / chain precursor molar ratio
- Atom Transfer Radical Polymerization uses transition metal salts associated with organic ligands and an initiator which is generally an organic halide; control of the polymerization is made possible by the reversible cleavage of the C-Halogen bond (Matyjaszewski K., patent application WO 96/30421).
- a drawback of this polymerization is that a large amount of metal remains in the reaction medium at the end of the polymerization. Otsu (Otsu et al., Makromol. Chem. Rapid Comm., 3.12 A 32, (1982), Otsu et al.
- the controlled nature of the reaction is due to the reversibility of the CS bond under UV irradiation. It is thus possible to obtain block copolymers.
- the activation / deactivation equilibrium constant is not very favorable with regard to the propagation speed, which has the consequence of generating relatively large molecular weight distributions.
- Controlled radical polymerization has an advantage over conventional radical polymerization when it comes to preparing low molecular weight and functionalized chains (reactive telomeres). Such polymers are sought after for specific applications such as, for example, coatings and adhesives.
- the fraction of chains with at most one functional site becomes significant when the average degree of polymerization is less than a threshold value (eg 20 or 30 ).
- a threshold value eg 20 or 30 .
- polymer is used to describe homopolymers or copolymers unless otherwise indicated.
- block polymer is understood to mean a copolymer comprising at least two successive sequences of blocks of monomer units of different chemical constitutions.
- the blocks can consist of a homopolymer or a polymer obtained from a mixture of ethylenically unsaturated monomers.
- the block can be a random copolymer.
- the block copolymer can comprise two blocks each made up of random copolymers.
- the ethylenically unsaturated monomers are such that the blocks obtained are of different natures.
- different natures is meant blocks made up of monomers of different types, but also blocks made up of monomers of the same type but in different quantities.
- An object of the present invention is to provide a new radical polymerization process using a new control agent.
- a second object of the invention is to propose a polymerization process during which the number-average molecular weights Mn of the polymers obtained are well controlled, these number-average molecular weights Mn increasing in number with the conversion of the monomer.
- Another aim is to propose a controlled radical polymerization process for the synthesis of functionalized polymers at the end of the chain.
- tetrathiophosphate group is meant a group of formula:
- the cyclic organic compound comprising at least one tetrathiophosphate group is chosen from a compound of formula (IA) (tetraphosphorus decasulfide or P 4 S 10 ) and a compound of general formula (IB):
- (IIA) (IIB) with R. represents an optionally substituted alkyl, aryl, aralkyl, alkene or alkyne group,
- a carbon ring or a heterocycle saturated or not, aromatic or optionally substituted
- n identical or different, an integer greater than or equal to 2.
- m is less than or equal to 5.
- the optionally substituted alkyl, aryl, aralkyl, alkene or alkyne groups generally have 1 to 20 carbon atoms, preferably 1 to 12, and more preferably 1 to 9 carbon atoms. They can be linear or branched. They can also be substituted in particular by oxygen atoms, in the form in particular of esters, sulfur or nitrogen atoms.
- alkyl radicals mention may in particular be made of the methyl, ethyl, propyl, butyl, pentyl, isopropyl, tert-butyl, pentyl, hexyl, octyl, decyl or dodecyl radical.
- the alkene radicals are radicals generally of 2 to 10 carbon atoms, they exhibit at least one ethylenic unsaturation, such as the vinyl or allyl radical.
- the alkyne groups are radicals generally of 2 to 10 carbon atoms, they exhibit at least one acetylenic unsaturation, such as the acetylenyl radical.
- aryl radicals mention may in particular be made of the phenyl radical, optionally substituted in particular by a nitro or hydroxyl function.
- aralkyl radicals mention may in particular be made of the benzyl or phenethyl radical, optionally substituted in particular by a nitro or hydroxyl function.
- R is a heterocycle
- the piperidine, morpholine, pyrrolidone or piperazine radical is preferred.
- R is a polymer chain
- this polymer chain can result from radical or ionic polymerization or result from polycondensation.
- the group R when substituted, may be substituted by substituted phenyl groups, substituted aromatic groups, saturated or unsaturated carbon rings, saturated or unsaturated heterocycles, or groups: alkoxycarbonyl or aryloxycarbonyl (-COOR ′), carboxy (-COOH), acyloxy (-
- R represents an alkyl or aryl group or a polymer chain.
- R is a substituted or unsubstituted alkyl
- the preferred alkyl radical is the radical of formula
- n is an integer greater than or equal to 2.
- the maximum value of m is 5.
- the groups R., in a compound of formula (IB) are identical.
- the groups R and R., in a compound of formula (IB) are identical.
- the compound (IB) useful in the present invention is for example a compound of formula (IB) in which R is chosen from:
- the compounds of formulas (IA) and (IB) have the advantage of being easily accessible.
- the compound of formula (IA) and certain reagents of formula (IB), such as the compound 2,4-bis (methylthio) -2,4-dithioxo-1, 3,2,4-dithiadiphosphetane, are commercial products.
- Certain reagents of formula (IB) can be obtained in particular by reaction between the compound of formula (IA) with at least one alcohol (ROH) or at least one thiol (RSH) (H. Davy, J. Chem. Soc, Chem. Commun., 457 (1982); G. Ohms et al. J. Chem. Soc. Dalton Trans. 1297 (1995); M. Démarcq J. Chem. Soc. Dalton Trans. 2221 (1988)).
- ROH alcohol
- RSH thiol
- the process of the invention is in all cases implemented in the presence of a source of free radicals, however, for certain monomers, such as styrene, the free radicals making it possible to initiate the polymerization can be generated by the " ethylenically unsaturated monomer, itself at sufficiently high temperatures generally above 100 ° C. It is not, in this case, necessary to add a source of additional free radicals.
- the source of free radicals useful in the process of the present invention is generally a radical polymerization initiator.
- the radical polymerization initiator can be chosen from the initiators conventionally used in radical polymerization. It can for example be one of the following initiators:
- - hydrogen peroxides such as: tertiary butyl hydroperoxide, eu hydroperoxide, t-butyl-peroxyacetate, t-butyl-peroxybenzoate, t-butylperoxyoctoate, t-butylperoxyneodecanoate, t- butylperoxyisobutarate, lauroyl peroxide, t-amylperoxypivalte, t-butylperoxypivalate, dicumyl peroxide, benzoyl peroxide, potassium persulfate, ammonium persulfate, - azo compounds such as: 2-2 ' -azobis (isobutyronitrile), 2,2'- azobis (2-butanenitrile), 4,4'-azobis (4-pentanoic acid), 1, 1'- azobis (cyclohexane-carbonitrile), 2- (t-butylazo) -2-cyanoprop
- - redox systems comprising combinations such as:. mixtures of hydrogen peroxide, alkyl, peresters, percarbonates and the like and of any of the iron salts, titanous salts, zinc formaldehyde sulfoxylate or sodium formaldehyde sulfoxylate, and reducing sugars,
- the amount of initiator to be used is determined so that the amount of radicals generated is at most 50% by mole, preferably at most 20% by mole, relative to the amount of cyclic organic compound comprising at least one tetrathiophosphate group.
- the ethylenically unsaturated monomers useful in the process of the present invention are all the monomers which polymerize in the presence of the cyclic organic compound comprising at least one tetrathiophosphate group to give active polymer chains.
- These ethylenically unsaturated monomers are for example
- - vinyl and vinylidene halides - ethylenic unsaturated mono- and dicarboxylic acids such as acrylic acid, methacrylic acid, itaconic acid, maleic acid, fumaric acid and the mono-alkyl esters of dicarboxylic acids of the type mentioned with the alkanols preferably having 1 to 4 carbon atoms and their N-substituted derivatives,
