Abstract
Three techniques of controlled radical polymerization, namely nitroxide-mediated radical polymerization (NMRP), atom transfer radical polymerization (ATRP), and reversible addition-fragmentation chain transfer (RAFT) polymerization in combination with ring opening polymerization (ROP) were employed to prepare functional block-copolymers with controllable molecular weight and narrow molecular weight distribution. The structure, molecular weight, and PDI of block-copolymers were characterized by various techniques. The synthesis routes of NMRP-ROP, ROP-ATRP, and ROPRAFT exhibited excellent controllable features in the preparation of functional block-copolymers.
