Synthesis of acrylic or methacrylic acid/acrylate or methacrylate ester polymers using pervaporation

摘要

The present invention relates to the synthesis of copolymers or terpolymers, in particular poly(acrylic acid-co-acrylate ester), poly(methacrylic acid-co-methacrylate ester), poly(acrylic acid-co-acrylate ester(I)-co-acrylate ester(II)) or poly(methacrylic acid-co-methacrylate ester(I)-co-methacrylate ester(II)), by esterification of polyacrylic or polymethacrylic acid with alcohols assisted by the pervaporation technique for extracting water.
