  • High tear strength polymers
    Patent number: 4363904
    Abstract: Heterogeneous ethylene based hydrocarbon copolymers having high tear strength properties in film form, formed from ethylene, C.sub.3-4 monomer and C.sub.5-8 monomer with a molar ratio in the polymer of (C.sub.3-4 /C.sub.2) of about 0.006 to 0.09, a (C.sub.5-8 /C.sub.2) ratio of about 0.003 to 0.07 and having a Chain Branch Factor of about 0.2 to 0.8 and a narrow molecular weight distribution; a gas phase process for making such polymers, and film made from such polymers.
    Type: Grant
    Filed: March 23, 1981
    Date of Patent: December 14, 1982
    Assignee: Union Carbide Corporation
    Inventors: William A. Fraser, Norma J. Maraschin, Frederick J. Karol, Alexander J. Makai
