摘要: The invention provides polymers of Formulas I-III, such as polyesters and unsaturated polyesters, and crosslinked and copolymerized polymers thereof. The invention also provides methods to catalytically ring-open five-membered rings such lactones, lactams, and thiolactones, as via ring-opening polymerization. The polymerization products are recyclable and can be depolymerized back to their monomer form via thermolysis and acid or base catalysis.
