The disclosure provides an ethylene copolymer having a density of from 0.912 g/cmto 0.925 g/cm, a melt flow ratio (I/I) of from 20 to 30, and a normal comonomer distribution profile in a GPC-FTIR analysis, wherein the normal comonomer distribution profile has a slope of from &#x2212;3.5 to &#x2212;7.5, where the slope is defined as the number of short chain branches per 1000 carbons at a molecular weight of 300,000 minus the number of short chain branches per 1000 carbons at a molecular weight of 30,000. The ethylene copolymers have improved bulk density and when made into film, provide good physical properties.

Ethylene copolymer having enhanced film properties

A method for altering the melt flow ratio (MFR) of ethylene copolymers made in a gas phase reactor using a supported Ziegler-Natta catalyst treated with a catalyst modifier. The method involves changing the amount of the catalyst modifier added to the supported Ziegler-Natta polymerization catalyst to effect changes in the MFR of the resulting polymer.

Method for altering melt flow ratio of ethylene polymers

Ethylene/1-butene copolymers made with a single site catalyst system have high melt strength and good processability.

Ethylene/1-butene copolymers with enhanced resin processability

The feed rate of a supported particulate catalyst through a unit body rotary disc catalyst feeder may be controlled by controlling the feed of nitrogen to the upper surface of the rotary disc.

Control over catalyst particulate feed into an olefin polymerization reactor

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

A polymer blend comprising first and second polyethylene copolymers is presented which has good processability, and which when made into film shows good toughness-stiffness balance, reasonable MD tear, as well as good optical properties.

Polyethylene blend compositions and film

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.
