Definitions
- TECHNICAL FIELD-The present invention relates to a method for producing a lactone polymer, a carbonate polymer, a lactone-strength-carbonate block copolymer, and a lactone-carbonate random copolymer using a specific polymerization catalyst.
- the present invention relates to monodispersion, that is, a molecular weight distribution value (Mw / Mn) represented by a ratio of a weight average molecular weight (Mw) to a number average molecular weight (Mn) is almost equal to 1 or Production method of lactone polymer, carbonate polymer, lactone-carbonate block copolymer, lactone-carbonate random copolymer with very high purity of one structural component, and lactone using initiator in extruder And a method for producing a lactone polymer, a carbonate polymer, a lactone-strength-carbonate copolymer, and a lactone polymer having a narrow molecular weight distribution obtained by the method.
- the present invention relates to a polymer, a lactone-force copolymer.
- Ring-opening polymerization of cyclic monomers such as lactones and cyclic carbonates is usually carried out using anion polymerization using an organometallic compound as an initiator, and using a compound having active hydrogen such as water or alcohol as an initiator, and using a catalyst as a catalyst.
- anion polymerization using an organometallic compound as an initiator and using a compound having active hydrogen such as water or alcohol as an initiator, and using a catalyst as a catalyst.
- a catalyst as a catalyst.
- organometallic compound as the initiator of the anion polymerization examples include n -butyllithium, tert-butoxypotassium, sodium methoxide, rare earth metal compound complexes, and the like.
- No. 737 discloses the synthesis of polystyrene-polyprolactone block copolymer and the like.
- No. 6 discloses synthesis of polyprolactone-polyneopentylglycol-carbonate block copolymer and the like, and JP-A-5-500982 and JP-A-5-2471184 disclose rare earth metals. The synthesis of polyprolactones using complexes has been reported.
- polymers and narrow block copolymers with narrow molecular weight distributions are obtained by employing special reaction methods such as very strict purification of the solvent and cyclic monomer used. There is an advantage that can be synthesized.
- Examples of the catalyst used in the latter polymerization include sulfuric acid, paratoluenesulfonic acid, quaternary ammonium salt, boron trifluoride, tin tetrachloride, trialkylaluminum, tetrabutyl titanate, and dibutyl tin oxide in a broad sense. Can be illustrated. These various Lewis acids serve to reduce the energy required for the ring opening reaction of lactone monomers and cyclic carbonate monomers, and to amplify the nucleophilicity of initiators such as water and alcohol.
