Abstract: The present disclosure relates to a method for the emulsion polymerization of itaconic acid containing ester functionality, for example, the alkyl esters of itaconic acid known as alkylitaconate. More specifically, an ester of polyitaconic acid polymer is produced via emulsion polymerization and contains greater than 50% by weight of an ester of itaconic acid along with a selected particle size and levels of molecular weight and syndiotactacticity.
