Title:
POLYVINYL CHLORIDE-POLYSTYRENE BLOCK COPOLYMER, POLYVINYL CHLORIDE-POLYVINYL ACETATE BLOCK COPOLYMER AND THEIR PRODUCTION
Document Type and Number:
Japanese Patent JP2000264937
Kind Code:
A
Abstract:
To obtain a polyvinyl chloride-polystyrene block copolymer, a polyvinyl chloride-polyvinyl acetate block copolymer both having excellent physicochemical properties, and a method for producing them.
This block copolymer is an AB-type polyvinyl chloride- polystyrene block copolymer or polyvinyl chloride-polyvinyl acetate block copolymer and is obtained by initiating a polymerization reaction by light-irradiating to vinyl chloride monomer using benzyl N,N-diethyldithiocarbamate as a radical polymerization initiator, generating a polyvinyl chloride and initiating a polymerization of styrene or vinyl acetate by light-irradiating to the polyvinyl chloride and styrene or vinyl acetate.
