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 40% mass loss within 6 hours of UV exposure (365 nm) for only 3% of sulfur-containing linkages.
