ABSTRACT:
Novel 2:1 copolymers of maleic anhydride and cyclic conjugated dienes such as cyclopentadiene. The saturated copolymers are prepared by heating the cyclic diene and maleic anhydride in the presence of a free radical precursor, such as a peroxygen compound, at a temperature at which the catalyst half life is no more than 2 hours.
