Abstract: A pressure sensitive adhesive which is prepared by emulsion polymerizing an ethylenically unsaturated monomer and 0.01 to 2 pphm of a sterically hindered alkoxylated silane monomer. The silane crosslinks during film formation to provide the adhesive with increased shear strength without the disadvantage of decreased loop tack. The sterically hindered alkoxylated silane monomer has the structure R1—Si—(OR2)n(R3)3−n wherein R1 is selected from the group consisting of an alkylene, arylene, and aralkylene group; R2 is independently a sterically hindered alkyl group having 3 to 10 carbon atoms in a straight or branched chain configuration; R3 is a monovalent alkyl group having 1 to 10 carbon atoms; and n is an integer of from 1 to 3.

Abstract: Wet adhesion properties comparable or superior to all-acrylic latexes for vinyl acetate copolymers and other low cost polymers, such as EVA-vinyl chloride copolymers, is achieved by blending a minor proportion, usually about 5 to 15%, of a small particle size copolymer containing copolymerized wet adhesion monomer which is a cyclic ureido. Very low quantities of the wet adhesion monomer, less than 0.25 wt% of total monomers, only are required to achieve excellent results.

Abstract: Disclosed are aqueous latex-based coating compositions which comprise a blend of an ethylene-vinyl acetate emulsion copolymer component and a selected type of acrylic emulsion copolymer component. The acrylic copolymer component comprises primarily acrylate ester co-monomers or acrylic ester co-monomers and vinyl aromatic, e.g., styrene, co-monomers. The blend of these two emulsion copolymer types also contains a specific type of hydrazine-based, water-soluble cross-linking agent which can eventually react with the acrylic emulsion copolymer component. The acrylic emulsion copolymer is one which contains minor amounts of both 1) carboxy functional co-monomers such as itaconic and/or (meth)acrylic acids, and 2) keto- or aldehyde-containing co-monomers such as diacetone acrylamide. Such latex-based coating compositions can be formulated in the form of water-based paint compositions. These paint products provide paint coatings that exhibit desirable dry and wet adhesion characteristics and desirable resistance to blocking.

Abstract: A solution with a salt-sensitive polymer binder for use in fibrous webs, where the binder contains a copolymer of carboxylic acid monomer units and ethylenically unsaturated monomer units. The binder solution is prepared by emulsion-polymerizing a copolymer and then neutralizing the copolymer with base to make it water soluble. The binders provide a higher wet strength in concentrated salt solutions than in deionized water, and are particularly suitable for strengthening nonwoven fibrous webs in disposable articles such as wet-wipes, personal care products, diapers, and the like.
