    Abstract: A method for the homopolymerization of maleic anhydride which comprises the controlled addition of a heated mixture of maleic anhydride, a polymerization initiator and a solvent for the monomer but not the polymer to a heated reaction zone containing a dilute solution of maleic anhydride in the identical solvent whereby the polymerization of the monomer and the precipitation of the polymer occur virtually simultaneously upon introduction of the feed monomer into the reaction zone. Maleic anhydride homopolymer and derivatives thereof may be effectively utilized in a wide variety of applications and, notably, as detergent builders and surface active agents.
