  • Pumpability sealant composition
    Patent number: 5118531
    Abstract: A pumpable sealant composition comprises of (A) ethylene/propylene nonconjugated polyene terpolymer having a number average molecular weight of between about 4,000 and about 15,000; (B) ethylene/propylene copolymer having a number average molecular weight of between about 500 and about 5,000; (C) an effective amount of curative; (D) (optionally) filler; and (E) (optionally) a blowing agent; which composition possesses a Brookfield viscosity of between about 100,000 and about 5,000,000 centipoise at shear rates of 5 reciprocal seconds or greater at 22.degree. C. Also disclosed is a method of protecting a substrate employing such composition.

  • Carboxyl modified olefinic copolymer compositions
    Patent number: 4888393
    Abstract: The invention relates to a novel low profile additive (LPA) for uncured polyester resins and the resultant molding compositions. The low profile additive is the reaction product of an ethylene/alphaolefin copolymer with a carboxylic acid or anhydride, to thereby form a non-thermoplastic carboxyl modified polyolefin. The novel LPA is a remarkably effective dimensional stabilizer and has displayed the ability to achieve net expansion in a cured polyester resin molding composition.

  • Thermoplastic elastomer containing long chain aliphatic alcohol
    Patent number: 4239862
    Abstract: Long chain aliphatic alcohol (C.sub.16 +) is added to thermoplastic elastomer based on blend of olefin copolymer rubber (EPM or EPDM) and polyolefin resin (especially polypropylene). The blend may be uncured or dynamically partially cured. The long chain aliphatic alcohol permits injection molded articles to be demolded within a shorter time without tearing or distortion, and decreases the surface tackiness of the article.

  • Thermoplastic elastomer composition
    Patent number: 4202801
    Abstract: Dynamically partially cured blends of monoolefin copolymer rubber with a polyolefin resin and a conjugated diene rubber are thermoplastic and can be fabricated into useful articles by conventional processing methods such as injection molding or extrusion.
