UV cured polymer based on a renewable cardanol derived RAFT agent

A cardanol-derived reversible addition-fragmentation chain transfer (RAFT) agent was synthesized in 57 % total yield, and a cardanol-based anionic surfactant was also facilely prepared. Emulsion polymerization of methyl methacrylate (MMA) was realized to form a cardanol-terminated PMMA polymer by using the novel RAFT agent as well as the cardanol-based anionic surfactant. To improve the properties of cardanol-terminated PMMA as a material, UV-curing was performed. According to the comprehensive behavior of the UV-cured resins, optimal irradiation time was 20 min.
