摘要： Ethylene copolymers having a relatively high melt flow ratio and a multimodal profile in a temperature rising elution fractionation (TREF) plot are disclosed. The copolymers can be made into film having good dart impact values and good stiffness properties under decreased extruder pressures.

摘要： Ethylene copolymers having a relatively high melt flow ratio, a multimodal profile in a temperature rising elution fractionation (TREF) plot, a reverse comonomer distribution profile, and a composition distribution breadth index CDBI
50 of from 35 wt% to 70 wt%, as determined by TREF, are disclosed. The copolymers can be made into films having good dart impact values and good stiffness properties under decreased extruder pressures. Preferably, the copolymers are prepared by a polymerization process involving a supported group 4 phosphinimine catalyst.

摘要： Ethylene copolymers having a relatively high melt flow ratio and a multimodal profile in a temperature rising elution fractionation (TREF) plot are disclosed. Such polymers are produced from a gas phase single reactor process where a phosphinimine-ligated group IV metallocene catalyst is used. The copolymers can be made into film having good dart impact values and good stiffness properties under decreased extruder pressures.
