Radical polymerization of acenaphthylene (Ace) as a 1,2‐disubstituted ethylene was investigated. It was found that the polymerization rate ( R p ) was expressed as follows: R p = k [Ace] 1.0 [AIBN] 0.68 , and that the overall activation energy was 113 kJ/mol for polymerization with 2,2'‐azobisisobutyronitrile (AIBN) in benzene at 50–70°C. Poly(Ace) obtained was characterized by NMR spectroscopy and GPC. Some substituted copolymethylenes were also prepared by radical copolymerization of Ace with other 1,2‐disubstituted ethylenes, that is, maleic anhydride, diisopropyl fumarate, and N ‐cyclohexylmaleimide. The monomer reactivity ratios were determined from comonomer–copolymer composition curves.
