Abstract
The copolymerization of itaconic anhydride and vinyl chloride has yielded copolymers with itaconic anhydride much richer than that in the feed. The rate of the homopolymerization of itaconic anhydride has been compared with the rates of itaconic esters, obtaining the following order: di-2-ethylhexyl ester > anhydride > dimethyl ester. The infrared spectra and solubility character of the polymer have been shown in comparison with those of the monomer. Further, polyitaconic acid has been obtained by the hydrolysis of polyitaconic anhydride with some ease.
