Preparation of P- and S-Containing UV-Cured Cardanol Polymers via Thiol-ene Click Chemistry

摘要

Tricardanolic phosphite was synthesized in 65% yield. This cardanol-derived small molecular compound was successfully transformed into UV-cured resin via thiol-ene click reaction, by using 4,4'-di(mercaptomethyl)benzophenone as both a photoinitiator and a crosslinker. The fully bio-based P- and S-containing resin is expected to be flame-retardant materials.
