A fluid dynamic model having at least 5,000,000 cells of the portion of a gas phase reactor from the exit of the condenser to a half a reactor diameter above the bed plate is useful in determining the design of the bottom surface or support structure for a bed plate to minimize liquid pooling below and above the bed plate when operating in condensing mode.

Molding a bed plate and its use

A polymerization process for stable gas phase reactor start-up when making ethylene copolymers having relatively high molecular weight distribution and melt flow ratio.

Process for polymerization in a fluidized bed reactor

Ethylene copolymers having a relatively high melt flow ratio and a multimodal profile in a temperature rising elution fractionation (TREF) plot are disclosed. The copolymers can be made into film having good dart impact values and good stiffness properties under decreased extruder pressures.

Ethylene copolymer compositions, film and polymerization processes

Ethylene copolymers, film and polymerization process

Olefin polymerization is carried out with a supported phosphinimine catalyst which has been treated with a long chain substituted amine compound.

Modified phosphinimine catalysts for olefin polymerization

Methods for dramatically altering the processability of ethylene copolymers made with a supported phosphinimine polymerization catalyst. The method involves changing the polymerization reactor temperature during the polymerization of ethylene and a least one alpha-olefin when a phosphinimine catalyst which comprises a substituted or unsubstituted indenyl ligand and a phosphinimine type ligand.

Controlling resin properties in a gas phase polymerization process

A scavenger is used to indirectly control the ratio of polymer components in a polyethylene composition made using a combination catalyst comprising an inorganic chromium catalyst, and a group 4 single site catalyst.
