Process for producing epsilon-caprolactone-modified hydroxyalkyl acrylate or methacrylate and coating copolymer from the same

摘要

epsilon -caprolactone-modified hydroxyalkyl acrylate or methyacrylate can be effectively produced from epsilon -caprolactone and a hydroxyalkyl acrylate or methacrylate in the presence of a stannous halide as a catalyst. The obtained monomer is used together with another copolymerizable monomer to produce a copolymer which is suitable for coating and photocurable composition.
