摘要：
Symmetrical amphiphilic triblock (BAB-type) copolymers carrying ATRP initiating groups were synthesized in 3 steps. Poly(hydroxyethyl acrylate) (pHEA) was synthesized first using bifunctional bis(trithiocarbonate) as a RAFT agent. In the second step, the chain was extended by the block of poly(butyl acrylate) (BuA). Finally, hydroxyl groups of the block copolymer were modified by 2-bromoisobutyryl bromide. The block copolymers are suitable as polyinitiators for the synthesis of molecular brushes by ATRP.
