ABSTRACT An unsaturated poly (alpha-hydroxy acid) copolymer is prepared by reacting a cyclic diester of an alpha-hydroxy acid having 2 to 5 carbon atoms with an ethylenically-unsaturated epoxide. The re- action is conducted at a temperature of 50 to 250°C in the presence of an effective amount of a ring- opening catalyst and an effective amount of a free- radical polymerization inhibitor. These copolymers are useful in forming plastic items in combination with fiber glass or other reinforcing materials. They are also useful as coatings and laminates.
