Synthesis of Comb-coil Type Block Copolymers via Controlled Radical Polymerization |
| 초록 |
Introduction of a grafted architecture into a specific block of the linear diblock copolymers produces “comb-coil” type block copolymers (CCBCP). CCBCPs having an A-b-B-g-C type architecture can be considered as a class of hybrid block copolymers that have the structural characteristics of both linear diblock copolymers and densely grafted polymers. In this study, PEO-b-PBPEA-g-PS was synthesized by combination of reversible addition-fragmentation chain transfer (RAFT) polymerization and atom transfer radical polymerization (ATRP). Use of a synthesized chain transfer agent consisting of a PEO segment in the polymerization of BPEA readily yielded a diblock copolymer consisting of initiating sties for ATRP on a specific block. Grafting of polystyrene was conducted via ATRP to produce the desired architecture. Detailed synthesis and characterization of synthesized polymers will be discussed. |
