Abstract

This disclosure concerns copolymers of ethylene and at least one C4-C12 monomer, and also concerns the production and application of these copolymers. These copolymers may be produced using supported metallocene catalysts in a gas phase polymerization process.
These copolymers can be produced to have composition distributions intermediate dose of polyethylene resins derived from Ziegler-Natta catalysts and those of single site catalysts. The polyethylene resins of the disclosure are particularly useful in producing films and in certain other applications.
