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.
聚氧烷基泡沫稳定剂可通过在自由基聚合条件下,在自由基引发剂的存在下,通过反应聚氧烷基加合物、环状氮基乙烯单体和酯化不饱和二元酸制备,并将所得反应产物进行溶剂萃取。隔离的组分可用作生产细胞泡沫的表面活性剂。
