Disclosed is an improved method of making polymers. The method utilizes at least one ethylenically unsaturated monomer and at least one polymerizable surface active agent. The polymerizable surface active agent is capable of co-polymerization with traditional monomers and/or polymerization with itself (i.e. homopolymerization) and is preferably substantially completely consumed during the course of the polymerization. Polymers produced by the method of the present invention are well suited for use in coatings, adhesives, sealants, elastomers and the like, as they form stable films, possess excellent adhesion properties and have improved hydrolytic stability characteristics. The present invention also encompasses homopolymeric surface active agents and their use in polymerization reactions.
本发明公开了一种改进的聚合物制造方法。该方法利用至少一种乙烯基不饱和单体和至少一种可聚合表面活性剂。可聚合表面活性剂能与传统单体共聚合和/或与自身聚合(即均聚),最好在聚合过程中完全消耗。用本发明的方法生产的聚合物非常适合用于涂料、粘合剂、密封剂、弹性体等,因为它们能形成稳定的薄膜,具有优异的粘合性能和更好的水解稳定性。本发明还包括均聚物表面活性剂及其在聚合反应中的应用。
