  • Patent number: 4038454
    Abstract: A novel cured pressure-sensitive adhesive-coated sheet material comprising a flexible backing having bonded thereto a pressure-sensitive adhesive material containing copolymers of 2-ethyl hexyl acrylate, butyl acrylate and glycidyl acrylate or glycidyl methacrylate. The monomer-mixture for the pressure-sensitive adhesive material may also contain minor amounts of monomers with acid anhydride groups or monomers with carboxyl groups. The curing of the pressure-sensitive adhesive material is accomplished by heating the copolymers to a temperature between 60.degree. and 100.degree. C., in the presence of a zinc chloride catalyst whereby the copolymers become cross-linked to obtain a solvent-, heat- and weather-resistant pressure-sensitive adhesive-coated sheet material.

  • Patent number: 4005247
    Abstract: Pressure-sensitive adhesives having improved cohesive strength are obtained by reacting an acrylic interpolymer containing an interpolymerized acrylic monomer containing an ethylenically unsaturated carboxylic acid anhydride with a metal alkoxide, chelated metal alkoxides such as chelated titanium esters being particularly preferred. Adhesives produced in this manner have improved cohesive strength on backings while maintaining good tack and adhesive properties.

  • Patent number: 3959537
    Abstract: A decorative molding having its body and under surface formed of a thermoplastic material which is bondable dielectrically with compatible materials carries bonded to such under surface a longitudinally extending composite fabric tape of a width less than that of the molding, the tape having on its underside a heat reactive adhesive compatible with and bondable to materials with which the body itself is incompatible.

  • Patent number: 3939131
    Abstract: A copolymer of 2,4-dimethyl-4-vinyl-1-cyclohexene and at least one member of the group consisting of 2,6- and 3,6-dimethyl-1,3,6-octatrienes, which copolymer is suitable for use as a tackifier, said copolymer consisting essentially of (A) structural units derived from 2,4-dimethyl-4-vinyl-1-cyclohexene and (B) structural units derived from at least one member selected from the group consisting of 2,6- and 3,6-dimethyl-1,3,6-octatriene in proportions of 100 moles of (A) to 1 to 400 moles of (B) and characterized by containing not more than seven unsaturated double bonds per 100 carbon atoms contained in its molecule and having a softening point of 85.degree.-160.degree.C. and an average molecular weight of 450-1850 is disclosed.
