Novel polyethylene copolymer compositions prepared with a homogeneous catalyst system are characterized by having a unique high molecular weight, low comonomer (high density) fraction. These heterogeneous/homogeneous compositions may be prepared using a solution polymerization process in which the polymerization reactor contains a gradient in temperature, catalyst concentration or monomer concentration. The heterogeneous/homogeneous compositions of this invention are easily processed into films having excellent tear strengths and low hexane extractables.
