PURPOSE:To provide a method for efficiently obtaining a caprolactone-modified hydroxyalkyl acrylate or methacrylate, useful as a coating monomer, good in color tone and excellent in preservation stability in a short time. CONSTITUTION:Ring opening polymerization of caprolactone is carried out using a hydroxyalkyl acrylate or methacrylate to produce a caprolactone- modified hydroxyalkyl acrylate or methacrylate. In the process, a titanium compound is used as a catalyst for the ring opening polymerization reaction and the resultant reaction product is subjected to treatment with active carbon. |
