摘要：

Block copolymer synthesis via a combination of ATRP and RAFT using click chemistry is reported for the first time. A RAFT agent with a terminal propargyl group (PTTC) was synthesized and was used to polymerize butyl acrylate and gave quantitative monomer conversion. Azide-terminated p(tbA) was obtained by ATRP followed by reaction with sodium azide. Later, using CuBr-PMDETA as catalyst via click chemistry, p(tBA)((ATRP)) and p(BA)((RAFT)) were reacted to get a block copolymer of p(tBA)((ATRP))-b-p(BA)((RAFT)). Further, a total of 24 block copolymers were made by reacting four azido functional polymers with six propargyl functional polymers to obtain block copolymers via click chemistry.
