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 NiCl 2 (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).
