Method for producing propylene / ethylene copolymer |
| abstract |
An object of the present invention is to provide a method for producing a propylene / ethylene copolymer with high polymerization activity using an olefin polymerization catalyst containing a metallocene compound. An olefin polymerization catalyst containing titanium, zirconium, or hafnium as a transition metal and having a structure having no plane of symmetry containing the transition metal is used, and a polymerization temperature of 50 to 150 ° C. A method for producing a propylene / ethylene copolymer having a content of ethylene units in the copolymer of 0.1 to 50 mol% and an intrinsic viscosity of 2 to 12 dl / g in the above range.
