Polyethylene compositions described herein have a density from about 0.900 g/cmto about 0.950 g/cm, a MI (I, 190&#xb0; C., 2.16 kg) from about 0.1 g/10 min to about 10 g/10 min, an MIR (I/I) from about 25 to about 80, an Mgreater than or equal to about 150,000 g/mol, and either an M/Mratio greater than or equal to about 8.0, an M/Mratio greater than or equal to about 2.4, or an (I*M/M) from about 3 to about 100. The polyethylene compositions are useful in wire and cable, tape, and filament applications, and could be produced using a gas phase or slurry phase, preferably gas phase, polymerization process.

Methods to produce heterogeneous polyethylene granules, the method including: contacting first olefin monomers and second olefin monomers with a catalyst system in a single reaction zone to produce heterogeneous polyethylene granules and recovering the heterogeneous polyethylene granules; wherein the catalyst system includes a product of a combination including: one or more catalysts having a Group 3 through Group 12 metal atom or lanthanide metal atom; at least one activator; and optionally, one or more support material compositions; and wherein the heterogeneous polyethylene granules include a product of a combination of: a first portion comprising a first polyethylene including the first olefin monomers and the second olefin monomers; a second portion including a second polyethylene including the first monomers and the second monomers; and wherein the first polyethylene has a higher second monomer weight percent than the second polyethylene, are provided.
