Synthesis and controlled polymerization of p-(1-methylcyclohexyloxy)styrene and quick-response deblocking ability of the obtained polymer

摘要

p-(1-Methylcyclohexyloxy)styrene (PC6ST) was synthesized by acid catalyzed addition reaction of p-bromophenol with 1-methylcyclohexene, followed by Grignard coupling with vinyl bromide catalyzed by NiCl2(dppp). Radical polymerization of PC6ST in the presence dr absence of TEMPO afforded poly(PC6ST) with narrow molecular weight distribution without the elimination Of the protective group. The obtained poly(PC6ST) showed a higher deprotection ability in response to external stimulation such as an acid compared with poly(p-tert-butoxystyrene). References: 15
