US 8,541,508 B2 · Epoxy group-containing copolymer, epoxy (meth)acrylate copolymer using the same and their production processes

Abstract

According to the present invention, a novel epoxy group-containing copolymer, including a production process thereof, and an epoxy (meth)acrylate copolymer starting from the epoxy group-containing copolymer, including a production process thereof are provided. The epoxy group-containing copolymer of the present invention contains a specific epoxy group-containing repeating unit and an olefin-based repeating unit. A novel epoxy (meth)acrylate copolymer of the present invention is produced by reacting the epoxy group-containing copolymer with (meth)acrylic acid.
