Abstract: Normally tacky, pressure sensitive adhesive compositions comprise one or more polymers having a T.sub.g of about 0.degree. C. or less containing at least about 40 weight percent polymerized, olefinically unsaturated carboxylic acid ester monomers and pendant functional groups attached to a polymer backbone and having the formula: ##STR1## in which R.sub.1 is a divalent organic radical at least 3 atoms in length, and X is organoacyl or cyano. Such polymers have markedly improved cohesive strength (shear holding value) with little or no detriment to adhesive tack or adhesion (peel resistnace), and these improvements are realized without the necessity of incorporating cross-linking monomers such as N-methylolamides or other cross-linking agents. Pressure sensitive adhesive, water-based emulsions containing such polymers and adhesive articles having at least a portion of one surface thereof coated with such adhesives are also provided.

Abstract: There are disclosed normally tacky, pressure-sensitive adhesive compositions comprising one or more normally tacky polymers having a T.sub.g of about 0.degree. C. or less and containing pendant functional groups attached to the backbone and having the formula: ##STR1## in which R.sub.1 is a divalent organic radical at least 3 atoms in length, and X is organoacyl or cyano, the polymers preferably also being normally tacky when cured. Such polymers have markedly improved cohesive strength (shear holding value) with little or no detriment to adhesive tack or adhesion (peel resistance), and these improvements are realized without the necessity of incorporating cross-linking monomers such as N-methylolamides or other cross-linking agents. Pressure-sensitive adhesive, water-based emulsions containing such polymers and pressure-sensitive adhesive articles comprising a substrate having at least a portion of one surface thereof coated with the adhesive compositions are also disclosed.

Abstract: There are disclosed normally tacky, pressure-sensitive adhesive compositions comprising one or more normally tacky polymers having a T.sub.g of about 0.degree. C. or less and containing (a) at least about 40 weight percent of at least one polymerized olefinically unsaturated carboxylic acid ester monomer in the polymer backbone and (b) pendant functional groups attached to the backbone and having the formula: ##STR1## wherein R.sub.1 is (i) a covalent bond which directly connects the carbonyl carbon atom of the --CHO group to a carbon atom in the backbone of the polymer or (ii) a divalent organic radical comprising a carbon atom which directly adjoins the carbonyl carbon atom of the --CHO group, the polymers also being normally tacky when cured.

Abstract: Binder, coating, and adhesive compositions having surprising film build, flow, leveling, and adhesive wet tack are provided by an aqueous dispersion comprising polymer particles having a central core surrounded by lobes. Also disclosed are the uses and process of preparation of these unique particles.
