  • Adhesive for difficult to bond surfaces
    Patent number: 6063858
    Abstract: Improved aqueous emulsion vinyl acetate-ethylene (VAE) polymer adhesives for use in packaging applications and on difficult to bond surfaces such as polyethylene, poly(ethylene terephthalate), and oriented polypropylene. The VAE polymers contain about 55-80 wt % vinyl acetate, 15-45 wt % ethylene, and 0-30 wt % of one or more additional ethylenically unsaturated copolymerizable monomer, based on the total weight of monomers. Cast films of the VAE emulsion polymers of this invention should have a tensile storage modulus (test frequency of 6.28 rad/sec) within the area encompassed by the following data points: 1.times.10.sup.5 and 2.times.10.sup.7 dynes/cm.sup.2 at 23.degree. C., and 1.times.10.sup.3 and 2.times.10.sup.6 dynes/cm.sup.2 at 70.degree. C.; preferably within the area encompassed by the following data points: 1.times.10.sup.6 and 1.5.times.10.sup.7 dynes/cm.sup.2 at 23.degree. C., and 3.times.10.sup.4 and 9.times.10.sup.5 dynes/cm.sup.2 at 70.degree. C.
