  • Method of coating rubber with a composition which resists removal by water
    Patent number: 4217395
    Abstract: A carboxylated polymer latex containing a minor amount by weight of a heat sensitizer sufficient to gel the polymer and which also can contain fillers, wetting agents and stabilizers can be used to provide a water resistant film on the surface of a hot rubber compound or composition which subsequently can be cooled rapidly with water and dried. The resulting latex coated rubber can then be stacked or assembled without sticking.

  • Compositions comprising EPDM, E/VA and poly-alpha-methylstyrene
    Patent number: 4102855
    Abstract: Blends of crystalline EPDM rubbery polymers, high m.w. ethylene-vinyl acetate copolymers and polyalphamethyl styrene exhibit good processing characteristics and physical properties. Part of the EVA may be replaced with low m.w. crystalline polyethylene. The addition of reinforcing agents will raise the modulus and other physical properties while still retaining favorable processing characteristics.
