ABSTRACT:
The present invention is directed to improved aqueous based pressure sensitive adhesive emulsion polymers. Conventional emulsion based pressure sensitive adhesives are comprised of a copolymer comprised of polymerized units of acrylic esters and ethylenically unsaturated monomers, the copolymer having a T.sub.g of from -15 to -70.degree. C. The improvement in the aqueous based, emulsion polymerized pressure sensitive adhesives resides in the incorporation of a vinyl C.sub.8-13 ester of a neo-acid into the copolymer present in the pressure sensitive adhesives. Such vinyl ester is formed from a mixture of propylene oligomers and such vinyl ester is represented by the chemical formula C.sub.8-13 H.sub.17-27 CO.sub.2 CH.dbd.CH.sub.2.
