Title:
PREPARATION OF ACRYLIC COPOLYMER
Document Type and Number:
Japanese Patent JP2008260891
Kind Code:
A
Abstract:

To provide a process for preparing an acrylic copolymer having a structural unit based on an acrylate monomer and a structural unit based on a norbornene monomer using a radical polymerization initiator at a temperature higher than the 10 hour half-life temperature of the initiator by 0-30C.

The preparation process of an acrylic copolymer comprises a step of copolymerization of (A) an acrylate monomer and (B) a norbornene monomer in the presence of (C) a Lewis acid and (D) a nickel compound using an azobis radical polymerization initiator with the polymerization initiating temperature and the peak temperature of the polymerization higher than the 10-hour half-life temperature of the radical polymerization initiator by 0-30C.
