Photoinitiation of polymerisation

Abstract

General features of photoinitiated free radical polymerisations are outlined with reference to the requirements for useful photocurable films and coatings. Initiation via charge transfer processes, including exciplex formation, is reviewed and details of photoinitiation of methyl methacrylate polymerisation by various amine-fluorenone combinations are presented. Results for polymerisations photoinitiated by small molecule fluorenones and copolymers derived from 2-vinyl fluorenone are compared in an attempt to establish detailed reaction mechanisms. © 1977, Walter de Gruyter.
