Abstract
A copolymer of a lactone and a polycyclic carbonate is prepared by heating a monomer of a lactone with a polycyclic carbonate having two cyclic structures including a carbonate group at elevated temperatures less than 200 degrees Centigrade in the presence of a catalyst. The described copolymers evidence excellent mechanical properties, good resorption velocity and do not disintegrate upon degradation into materials of high crystallinity.
