Abstract

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(__t__bA) was obtained by ATRP followed by reaction with sodium azide. Later, using CuBr‐PMDETA as catalyst via click chemistry, p(__t__BA)~(ATRP)~ and p(BA)~(RAFT)~ were reacted to get a block copolymer of p(__t__BA)~(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. magnified image
