Stable latices of polymer particles insoluble in non-polar organic solvents are prepared by the attachment of the insoluble polymer particles to a stabilizer soluble in the non-polar organic solvent. The stabilizer comprises the adduct of a polymer bearing pendant azlactone groups which is soluble in non-polar organic solvents and an ethylenically unsaturated nucleophile bearing an azlactone reactive nucleophilic moiety.
通过将不溶于非极性有机溶剂的聚合物颗粒附着到可溶于非极性有机溶剂的稳定剂上,制备出不溶于非极性有机溶剂的聚合物颗粒的稳定乳胶。稳定剂包括可溶于非极性有机溶剂的、带有唑内酯基团的聚合物与带有唑内酯活性亲核分子的
乙烯不饱和亲核剂的加合物。
