| Abstract: | 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 or 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). |
