Copolymers which can be fabricated into films, fibers and structural shapes are prepared by copolymerizing an optically inactive lactide, i.e., D,L-lactide, and epsilon caprolactone in the presence of a tin ester of a carboxylic acid. A copolymer prepared from 85 parts by weight of D,L-lactide and 15 parts by weight of epsilon caprolactone is a thermoplastic elastomer. A copolymer prepared from 90 parts by weight of D,L-lactide and 10 parts by weight of epsilon caprolactone is a rigid, clear, thermoplastic solid.
