A light-assisted RAFT copolymerization protocol is established and investigated for the synthesis of 2-hydroxyethyl acrylate (HEA) / spiropyran acrylate (SPA) copolymers with enhanced SPA-contents. Radiation with visible light prevents the spiropyran (SP) motif from isomerizing into the open merocyanine (MC) form which can interfere with the polymerization process by abstracting a hydrogen atom from an active radical via its phenolic oxygen.
