Abstract
Reversible addition-fragmentation chain transfer was applied to the copolym erization of methyl methacrylate and a methacrylate-terminated poly(dimethy lsiloxane) macromonomer (PDMS-MA). The relative reactivity of PDMS-MA (1/r( MMA)) was higher than in the conventional radical copolymerization and simi lar to that in the atom transfer radical copolymerization. The obtained gra ft copolymers had much lower polydispersities than those obtained in the co nventional radical systems.
