METHOD OF COPOLYMERIZING UNHINDERED CONJUGATED DIENES WITH MALEIC ANHYDRIDES

A method of producing high yields of gel-free copolymers of maleic anhydride and unhindered conjugated dienes comprising the step of reacting the conjugated diene and maleic anhydride in a batch reactor containing a solvent and a sparingly soluble free radical-generating catalyst.
