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.
