A series of polystyrene-b-(poly(2-(2-bromopropionyloxy) styrene)-g-poly(methyl methacrylate)) (PS-b-(PBPS-g-PMMA)) and polystyrene-b-(poly(2-(2-bromopropionyloxy) ethyl acrylate)-g-poly(methyl methacrylate)) (PS-b-(PBPEA-g-PMMA)) as new coil-comb block copolymers (CCBCPs) were synthesized by atom transfer radical polymerization (ATRP). The linear diblock copolymer polystyrene-b-poly(4-acetoxystyrene) and polystyrene-b-poly(2-(trimethylsilyloxy) ethyl acrylate) PS-b-P(HEA-TMS) were obtained by combining ATRP and activators regenerated by electron transfer (ARGET) ATRP. Secondary bromide-initiating sites for ATRP were introduced by liberation of hydroxyl groups via deprotection and subsequent esterification reaction with 2-bromopropionyl bromide. Grafting of PMMA onto either the PBPS block or the PBPEA block via ATRP yielded the desired PS-b-(PBPS-g-PMMA) or PS-b(PBPEA-g-PMMA). H-1 nuclear magnetic resonance spectroscopy and gel permeation chromatography data indicated the target CCBCPs were successfully synthesized. Preliminary investigation on selected CCBCPs suggests that they can form ordered nanostructures via microphase separation. (C) 2016 Wiley Periodicals, Inc.
