This study was designed to synthesize novel degradable polymers by radical addition-fragmentation ring-opening copolymerization of biobased thiocarbonyl compounds with various vinyl monomers. Thiocarbonyl l-lactide was capable of radical copolymerization with acrylates and styrene via radical addition to the carbon-sulfur double bonds followed by ring-opening as well as controlled copolymerization in conjunction with the RAFT process. The obtained polymers possessed ring-opened thioester and ring-retained thioacetal functionalities in the backbone, both of which could be cleaved under appropriate conditions with different chemical stimuli.
