ABSTRACT:
The invention provides a novel resin composition of polymers of ethylene capable of giving a shaped article having outstandingly excellent mechanical properties but yet having very good processability or moldability. The resin composition is composed of 15-90% by weight of a homopolymer of ethylene and 85-10% by weight of a copolymer of ethylene and characterized by several parameters including the intrinsic viscosity, density and swelling ratio as well as satisfaction of the relationships between the melt index and the intrinsic viscosity and between the melt index and the melt tension expressed by the respective logarithmic equations. Industrially feasible processes for the preparation of such resin compositions are described in detail.
