Radical ring-opening polymerization (rROP) of cyclic ketene acetals (CKAs) provides a chain-growth pathway to synthesize functional biodegradable polyesters. The unique physical properties of these CKA copolymers were studied with quartz-crystal microbalance (QCM), contact angle and surface tension measurements. The comprehensive characterization results demonstrate the potential of such materials to serve as active ingredients in sustainable home care formulations, capsules, coatings, and other products. The end-of-life degradability of CKA copolymers were evaluated under different conditions, in the presence of a base or enzymes, as well as in wastewater, and the underlying biodegradation mechanisms were investigated.
