Abstract

AbstractPoly(glycidyl methacrylate)‐block‐poly(4‐vinylbenzyl chloride), or P(GMA)‐b‐P(VBC), is synthesized via consecutive reversible addition‐fragmentation chain transfer (RAFT) polymerizations. Subsequent functionalization via atom‐transfer radical polymerization (ATRP) of methyl methacrylate (MMA) and styrene (St) gives rise to two functional brush‐type diblock graft copolymers, P(GMA)‐b‐(P(VBC)‐g‐P(MMA)) and P(GMA)‐b‐(P(VBC)‐g‐PS). These graft copolymers are further functionalized by a ring‐opening reaction of the P(GMA) block with diethylamine (DEA) to produce two diblock copolymer brushes, P(DEAHPMA)‐b‐(P(VBC)‐g‐P(MMA) and P(DEAHPMA)‐b‐(P(VBC)‐g‐PS (Brush‐2A). Single molecules of the copolymers are imaged by atomic force microscopy (AFM). Brush‐2A can be cast into porous membranes with well‐defined micropores from tetrahydrofuran (THF) solutions by phase inversion in an aqueous medium.
