ABSTRACT

Amphiphilic diblock copolymers of poly(furfuryl methacrylate) (PFMA) with cationic poly(2-(methacryloyloxy)ethyltrimethyl ammonium chloride) (PFMA-b-PMTAC) and anionic poly(sodium 4-vinylbenzenesulfonate) (PFMA-b-PSS) were prepared via reversible addition fragmentation chain-transfer (RAFT) polymerization by using PFMA as a macro-RAFT agent. The formation of the block copolymer was confirmed by FTIR and
