Definitions

  • Allyl ethers are in this context reaction products between polyhydric compounds, such as polyalcohols, and one or more allyl or methallyl halides or alcohols yielding ethers having one or more allyl and/or methallyl groups.
  • said polyhydric compound (I) is pentaerythritol or di-pentaerythritol, said polyhydric compound (II) is trimethylolpropane or di-trimethylolpropane, and said allyl or methallyl halide is allyl and/or methallyl chloride.
  • the process of the invention discloses that it is possible to dissolve large parts of for instance pentaerythritol in triols such as trimethylolpropane. Weight ratios between for instance 2:1 and 3:1 are possible. Said weight ratios can using allyl chloride as allyl compound yield a mixed allyl ether having an allyl functionality of between 2.5 and 2.8 within a process time, such as 4-6 hours, similar as the process time for pure trimethylolpropane and allyl chloride while the process time for pure pentaerythritol and allyl chloride typically is in the range 16-20 hours. This enables production of higher functional allyl compounds at a reduced process time.
  • allyl ethers exhibit significantly higher reactivity than comparable unsaturated polyesters based on the frequently used trimethylolpropane diallyl ether and close to those based on pentaerythritol triallyl ether. This can be used either to produce for instance unsaturated polyesters with a higher reactivity or a lower content of allyl functional ethers. Another possibility is to formulate to use less styrene which is generally desired from an environmental point of view.
  • the present invention refers to the use of a mixed allyl ether, obtainable by the process of the present invention, as crosslinker for acrylic polymers in acrylic thickeners and in superabsorbant polymers.

Abstract

La présente invention concerne un procédé d'allylation de composés polyhydriques mélangés comprenant au moins deux composés polyhydriques différents ayant chacun au moins 3 groupes hydroxyle. Selon le procédé, au moins un composé polyhydrique (II) ayant un point de fusion inférieur à 120 °C est utilisé en tant que milieu de solution et/ou en tant que support pour au moins un composé polyhydrique (I) ayant un point de fusion au moins égal à 150 °C, ledit composé polyhydrique (I) et ledit composé polyhydrique (II) dans un rapport molaire compris entre 1/3 et 3/1 étant soumis à une allylation à une température comprise entre 100 et 160 °C, par réaction avec au moins un composé allylique et/ou méthallylique.
