Abstract
A composition comprises (A) an exopy resin and (B) a vinyl polymer having a reactive functional group selected from the group consisting of an alcoholic hydroxyl, phenolic hydroxyl, amino, amido and carboxyl group prepared by living radical polymerization, particularly the atom transfer radical polymerization of a vinyl polymer having a halogen atom and conversion of the halogen atom to a reactive functional group.

An epoxy resin composition
- which comprises (A) an epoxy resin and (B) a vinyl polymer having a main chain produced by living radical polymerization and a reactive functional group selected from the group consisting of a phenolic hydroxyl, an amino group and an amide group at a main chain terminus, and wherein said
- vinyl polymer (B) is obtained by
- (1) producing a vinyl polymer having a halogen atom at a main chain terminus thereof by atom transfer radical polymerization and
- (2) converting said halogen atom to a substituent having a phenolic hydroxyl, an amino group or an amide group.
