Studies on stable free radicals. XIX. Copolymerization of N‐oxyl biradical with α‐chloro‐p‐xylylene

Abstract

Copolymerization of N‐oxyl biradical with α‐chloro‐p‐xylylene was carried out by varying the feed ratio of α,α′‐dichloro‐p‐xylene which was the precursor of α‐chloro‐p‐xylylene. The structures of the obtained copolymers were determined spectroscopically. The results that the N‐oxyl attacked the carbon‐bearing chlorine atom of α‐chloro‐p‐xylylene suggest a nucleophilic reactivity of N‐oxyl radical. The copolymerization process was also discussed.
