VINYL ETHER GROUP-CONTAINING COPOLYMER AND STAR POLYMER AND PRODUCTION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a method allowing easy production of a vinyl ether group-containing copolymer capable of being used as a reactive precursor of a star polymer by using a radical polymerizable vinyl monomer as a material in a one-step process.SOLUTION: A production method of a vinyl ether group-containing copolymer is characterized by comprising a process for producing a vinyl ether group-containing copolymer by heating a reaction liquid comprising a radical polymerizable vinyl monomer, a reversible addition cleavage-type chain transfer agent, a radical initiator and a divinyl ether compound.
