Lactide-derived monomers for radical thiocarbonyl addition ring-opening copolymerisation

Abstract

The six-membered DL-thionolactide and DL-dithionolactide are reactive in radical ring-opening copolymerisation with a series of vinyl monomers to yield chemically degradable polymers. Bleach is an excellent degrading agent for both thioester and thioacetal linkages compared to classical nucleophilic treatment with amines.
