New Addition-fragmentation Chain Transfer Agents for Radical Polymerization and reactivity of the macromonomers derived therefrom

摘要

Radical addition-fragmentation has long been known in organic chemistry to provide group transfer reaction to alkyl radicals ~(1,2). Since then ~(3,4), allylic sulfides have been recognized as remarkable chain transfer agents in radical polymerization. The chain termination is based on an addition-fragmentaton pattern as described below.
