Abstract: The copolymerisation of L-Lactide with a cyclic xanthate monomer derived from tri-O-acetyl-D-glucal has been used to incorporate thionocarbonate and thioester linkages into a polyester backbone. The poly(lactide-co-xanthate) copolymers show enhanced UV-degradability compared to PLA, with… read more here.
