The present invention relates to a water-based high-solids moisture-resistant latex pressure sensitive adhesive which has a low coating viscosity and which has high shear, high compliance, and controlled adhesion buildup.

High solids moisture resistant latex pressure-sensitive adhesive

The disclosed invention is an electrically conductive aqueous polymeric vehicular emulsion containing suspended electrically conductive material. The method for producing said composition and correlated compositions is also disclosed. The present invention is intended for an extensive range of applications, from EMI shielding to complex three-dimensional printed circuitry to electrochemical fuel cell sealants. The electrically conductive composition can also be altered to produce an electrically insulative composition.

Water-soluble electrically conductive composition, modifications, and applications thereof

Aqueous polymer latexes having total solids contents of nearly 70 volume percent or more are produced by a process in which a portion of a forming latex in a reaction zone is continuously withdrawn from the reaction zone during formation of a stable seed latex and an intermediate latex, and the withdrawn latex is continuously fed back to the reaction zone during the formation of the final latex.

High solids latexes

This invention relates to an aqueous emulsion polymer used as pigment dispersing agent comprising as copolymerized units the following monomers (A) an ethylenically unsaturated monomer containing at least one amino group; (B) an ethylenically unsaturated monomer containing no amino group; (C) optionally a hydroxy-or alkoxyalkyl(meth)acrylate of the formula CH2=CH(R1)-COO-CtH2t-OR2 wherein R1 is hydrogen or methyl and R2 is hydrogen or C1-C6alkyl and t is an integer of 2, 3, 4, 5 or 6; (D) a (poly)alkyleneglycolmono(meth)acrylate of the formula CH2=CH(R1)-COO-(CmH2mO)n-OR2 wherein R1 is hydrogen or methyl and R2 is hydrogen or C1-C6alkyl and m is an integer of 2 or 3 and n is an integer of 2 to 20.

Aqueous emulsion polymer as dispersant

Aqueous resinous composition comprising an emulsion of acrylic or butadiene polymers, which is prepared by emulsion polymerization in the presence of hydrolyzed vinyl acetate-alkali metal olefinsulfonate copolymer as an emulsifier, and a water-soluble polymeric material. The composition has excellent properties, particularly improved stability and good operation efficiency, and is applicable in wide uses, for instance, as binder, adhesive, textile treating agent and molded article.

Aqueous composition containing acrylic or butadiene polymers

HIGH SOLIDS AQUEOUS POLYMER EMULSIONS ARE PRODUCED BY FIRST ADMIXING A SURFACTANT WITH ONE OR MORE POLYMERIZABLE MONOMERS EACH CONTAINING AT LEAST ONE OLEFINIC DOUBLE BOND, TOGETHER WITH AN AMOUNT OF WATER CORRESPONDING TO BETWEEN ABOUT 6% AND ABOUT 25% BY WEIGHT BASED ON THE TOTAL WEIGHT OF MONOMER EMPLOYED. THE RESULTANT PRE-EMULSION IS THEN ADDED TO AN AQUEOUS MEDIUM AND POLYMERIZED IN THE REACTIVE PRESENCE OF A FREE RADICAL POLYMERIZATION CATALYST.
