What is Radical copolymerization of alkyl 2‐norbornene‐2‐carboxylate with alkyl acrylates: Facile incorporation of norbornane framework into poly(alkyl acrylate)s about?

## Abstract Radical copolymerization of alkyl 2‐norbornene‐2‐carboxylates (alkyl = Me **1a**, __n__Bu **1b**) with alkyl acrylates (alkyl = ethyl, methyl, and __n__‐butyl) was investigated. Copolymerization of **1a,b** with the alkyl acrylates initiated by 1,1′‐azobis (cyclohexane‐1‐carbonitrile) at 85 °C proceeded to give random copolymers, although the homopolymerization of **1a,b** did not proceed efficiently under the same conditions. Typically, bulk copolymerization of **1a** with ethyl acrylate in a feed ratio of 1:3 ([**1a**]:[EA]) afforded a copolymer with __M__~n~ = 33,300 containing 19.4 mol % of **1a** unit in the composition. An increase of __T__~g~ derived from the incorporation of the rigid norbornane framework was observed, although the extent of the temperature rise was rather moderate. The ternary radical copolymerization of **1a,b**/alkyl acrylate/__N__‐phenylmaleimide proceeded to give copolymers with the three repeating units in the main chain. © 2007 Wiley Periodicals, Inc.
