Abstract: An improved method of making CASE materials is provided, wherein the method utilizes a polymer latex derived from 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 is preferably substantially completely consumed during the course of the polymerization. Latex polymers produced by the method of the present invention are well suited for use in coatings, adhesives, sealants, elastomers. Additionally, the present invention relates to improved coating, adhesive, sealant and elastomer (CASE) materials utilizing polymer latexes derived from various monomers and ethylenically unsaturated amine salts of sulfonic, phosphoric and/or carboxylic acids.

Abstract: 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.
