PROCESS FOR PRODUCING BRANCHED POLYMER AND POLYMER

摘要

This invention is related to a production method of a branched polymer which comprises polymerizing a macromonomer ÄIÜ, said macromonomer ÄIÜ being a vinyl polymer obtainable by radical polymerization and terminally having one polymerizable carbon-carbon double bond-containing group per molecule. Furthermore, by producing the macromonomer by living radical polymerization, in particular atom transfer radical polymerization, it becomes possible to produce the above polymers or gels having well controlled side chain molecular weights..
