Aqueous laminating construction adhesive compositions incorporating a one-part adhesive copolymer, the copolymer being a vinyl ester/acrylic copolymer containing from about 0.1% to about 20%, by weight based on copolymer weight, of a copolymerized polar monomer, the copolymer having a Tg from about 10&deg; C. to about &minus;35 C. are provided which exhibit a good balance of high temperature and ambient temperature adhesion performance in a one-part adhesive composition.

Laminating construction adhesive compositions with improved performance

This invention is directed to compositions useful as ionomeric hot melt pressure sensitive adhesive compositions. These compositions comprise a polymer containing carboxylic acid, a miscible metal salt, and an o-methoxy-substituted aryl acid. These compositions display low melt viscosity, simplifying application, as well as improved adhesive properties, especially shear resistance.

Pressure sensitive hot melt adhesive

Aqueous, solution or emulsion, and solvent based compositions comprising a crosslinked vinyl addition polymer having methacrylaldimine crosslinking groups are useful as coatings, binders and adhesives. The polymers are prepared from a crosslinkable composition comprising (A) a vinyl addition homopolymer or copolymer of methacrolein and (B) a compound having at least two amine-function groups selected from primary amine and primary amine-generating groups. A method of use is described in which crosslinking is at ambient temperatures.
