High temperature polyethylene solution polymerization process

A catalyst composition comprising one or more metal complexes of a multifunctional Lewis base ligand comprising a bulky, planar, aromatic- or substituted aromatic-group and polymerization processes employing the same, especially continuous, solution polymerization of one or more &#x3b1;-olefins at high catalyst efficiencies are disclosed.

High temperature solution polymerization process

A catalyst composition comprising a zirconium complex of a polyvalent aryloxyether and a polymerization processes employing the same, especially a continuous, solution polymerization of ethylene and one or more Colefins or diolefins to prepare interpolymers having improved processing properties, are disclosed.

Polyolefin solution polymerization process and polymer

A catalyst composition comprising a zirconium complex of a polyvalent aryloxyether and the use thereof in a continuous solution polymerization of ethylene, one or more Colefins, and a conjugated or nonconjugated diene to prepare interpolymers having improved processing properties are disclosed.

Ethylene/&#x3b1;-olefin/diene solution polymerization process and polymer

The instant invention is a polyethylene film, and method of making the same. The polyethylene film according to instant invention includes at least one heterogeneously branched ethylene/&#x3b1;-olefin copolymer having a density in the range of about 0.910 to about 0.930 g/cm, a molecular weight distribution in the range of about 2.8 to 3.8, a melt index (I) in the range of about 0.3 to about 4 g/10 min, and an I/Iratio in the range of 6.5 to about 7.8. The film has a normalized dart impact strength of equal or greater than (6666-7012*density) g/mil, a normalized tear strength of equal or greater than (440*e&#x2212;(density&#x2212;0.915)/2*(0.00949)) g/mil, and a haze in the range of 3 to 10 percent. The method of making the polyethylene film according to instant invention includes the following steps: (1) providing at least one heterogeneously branched ethylene/&#x3b1;-olefin copolymer having a density in the range of about 0.910 to about 0.930 g/cm, a molecular weight distribution in the range of about 2.8 to 3.8, a melt index (I) in the range of about 0.3 to about 4 g/10 min, and an I/Iratio in the range of 6.5 to about 7.8; (2) processing the heterogeneously branched ethylene/&#x3b1;-olefin copolymer via blown film extrusion process or cast film extrusion process; and (3) thereby forming a film having a normalized dart impact strength of equal or greater than (6666-7012*density) g/mil, a normalized tear strength of equal or greater than (440*e&#x2212;(density&#x2212;0.915)/2*(0.00949)) g/mil, and a haze in the range of 3 to 10 percent.

Polyethylene films and method of making the same

A catalyst composition comprising a zirconium complex of a polyvalent aryloxyether and an alumoxane, polymerization processes employing the same, especially the continuous, solution polymerization of ethylene and one or more Colefins or diolefins to prepare copolymers having reduced cocatalyst by-product content, are disclosed.
