Abstract

PURPOSE: To prepare a copolymer useful as packaging films, etc. and having a specific density and melt index and excellent transparency, heat resistance, impact resistance and elasticity, by copolymerizing ethylene with propylene in gaseous phase in the presence of a Ziegler catalyst.
CONSTITUTION: A copolymer having a melt index of 0.01W10 and a density of 0.910W0.945 is prepared by copolymerizing ethylene with propylene (6W100mol% basis of ethylene) in gaseous phase, substantially free of a solvent, in the presence of a Ziegler catalyst comprising (A) a solid material consisting of a solid inorganic compound containing magnesium (e.g. magnesium metal, etc.), a titanium compound (e.g. titaniun tetrachloride, etc.) and/or a vanadium compound (e.g. vanadium tetrachloride, etc.), and (B) an organoaluminum compound.
