Title:
PROCESS FOR PRODUCTION OF POLYCARBONATE DIOL DIACRYLATE AND HIGH-PURITY POLYCARBONATE DIOL DIACRYLATE
Document Type and Number:
WIPO Patent Application WO/2011/122520
Kind Code:
A1
Abstract:
Provided is a process for producing a polycarbonate diol diacrylate from a polycarbonate diol and a vinyl acrylate compound without using a protonic acid or a metal component. A process for the production of a polycarbonate diol diacrylate, characterized by reacting a polycarbonate diol represented by general formula (I) with a vinyl acrylate compound represented by general formula (II) in the presence of a hydrolase; and a polycarbonate diol diacrylate represented by general formula (III), wherein the degree of terminal acrylation is 97% or more.
