ABSTRACT:
Polyoxyalkylene foam stabilizing surfactants can be prepared by reacting a polyoxyalkylene adduct, a cyclic nitrogenous vinyl monomer and an esterified unsaturated dibasic acid under free radical polymerization conditions in the presence of a free radical initiator, and by subjecting the reaction product obtained to a solvent extraction. The isolated components can be utilized as surfactants in producing cellular foams.
