CA 2338709

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 imvention 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.

L'invention concerne un procédé amélioré pour fabriquer des substances pour revêtements, agents de scellement, adhésifs et élastomères. Selon ce procédé, on utilise un latex polymère dérivé à partir d'au moins un monomère éthyléniquement insaturé et au moins un agent de surface polymérisable actif. L'agent de surface polymérisable actif est capable de copolymérisation avec des monomères traditionnels; il est, de préférence, entièrement consommé en cours de polymérisation. Les latex polymères obtenus selon le procédé de l'invention conviennent bien pour être utilisés dans des revêtements, des adhésifs, des agents de scellement et des élastomères. En outre, la présente invention concerne des substances pour revêtements, agents de scellement, adhésifs et élastomères utilisant des latex polymères dérivés à partir de divers monomères et de sels aminés éthyléniquement insaturés des acides sulfonique, sulfurique, phosphorique et/ou carboxylique.
