  • Radiation curable polyolefin pressure sensitive adhesive
    Patent number: 5209971
    Abstract: Pressure sensitive adhesive compositions comprise one or more poly(alpha-olefin) homopolymers, copolymers, terpolymers, and tetrapolymers derived from monomers containing 6 to 10 carbon atoms and photoactive crosslinking agents wherein radiation curing provides adhesive films having a superior balance of peel and shear adhesive properties and the pressure sensitive adhesive is useful in pressure sensitive adhesive tapes, in articles containing transfer adhesive films, and as the bonding material between supports in a laminated structure.
    Type: Grant
    Filed: February 3, 1992
    Date of Patent: May 11, 1993
