Title:
METHOD FOR PRODUCING BLOCK COPOLYMER
Document Type and Number:
Japanese Patent JP2006124595
Kind Code:
A
Abstract:
To provide a method for producing a (vinyl polymer-polylactone)-based block copolymer having good heat resistance.
This method for producing the block copolymer comprising a block segment (A) consisting mainly of a vinylic polymer and containing methacrylate units represented by the general formula (I) (R is norbornyl, adamantyl, or the like) and a block segment (B) consisting mainly of a polylactone comprises applying a living radical polymerization using a halogen-containing composite polymerization initiator to produce a polymer comprising the block segment (A) and finally obtaining the block copolymer comprising the block segment (A) and the block segment (B).
