Bimodal high-density polyethylene polymer compositions with increased high melt strength and good processability. The compositions comprise a base resin having a density of about 945 kg/mto about 955 kg/m, and an ethylene polymer (A) having a density of at least about 968 kg/m, in an amount ranging from 45% to 55% by weight and an ethylene polymer (B) having a density lower than the density of polymer (A). The composition has a complex viscosity at a shear rate of 0.01 rad/s ranging from about 200 to 450 kPa&#xb7;s and a complex viscosity at a shear rate of 100 rad/s ranging from about 1900 to 2500 Pa&#xb7;s. Articles made from these compositions, such as pipes and fittings achieve long-term oxidative resistance and have a low wall thickness variability while maintaining high production output.

Bimodal high-density polyethylene resins and compositions with improved properties and methods of making and using the same

The present disclosure is related to bimodal high-density polyethylene polymer compositions with increased high melt strength and good processability comprising a base resin which has a density of about 945 kg/mto about 955 kg/m, and comprises an ethylene polymer (A) having a density of at least about 968 kg/m, in an amount ranging from 45% to 55% by weight and an ethylene polymer (B) having a density lower than the density of polymer (A) wherein said composition has a complex viscosity at a shear rate of 0.01 rad/s ranging from about 200 to about 450 kPa&#xb7;s and a complex viscosity at a shear rate of 100 rad/s ranging from about 1900 to about 2500 Pa&#xb7;s. The present disclosure also relates to methods of making, and using the present compositions, and to articles made from there composition, and preferably to pipes and fittings.

The invention relates to an improved process for manufacturing an olefin polymer composition, in particular polyethylene, that incorporates two or more reaction zones in an optimized configuration that ease product transitions and allows for improved reactor quality control.

Operation of multi-reactor polyolefin manufacturing process

The present invention relates to the control of flow of a particulate feed to a reactor, and in particular provides a process for providing a slurry of particulate matter to a reactor, comprising providing a slurry comprising said particulate matter and diluent, and passing said slurry to the inlet of a reactor feed pump from where it is then pumped to the reactor, characterized in that a stream of additional diluent is also passed to the inlet of the reactor feed pump, the reactor feed pump is operated at an essentially constant volumetric flow rate, and the amount of particulate matter in slurry passed into the reactor is adjusted by adjusting the flow.

Particulate flow control process

The invention relates to an improved process for the manufacture of an olefin polymer composition in which corrosive trace cocatalyst and catalyst residues are removed from the hydrocarbon gas recycle stream prior to compression and re-use in the polymerization zone(s).
