Unimodal polyethylene copolymer and film thereof

A method of independently changing a melt rheology property value of a bimodal polyethylene polymer being made using a bimodal catalyst system in a single gas phase polymerization reactor. The method comprises process conditions comprising alkane(s) in the reactor. The method comprises a bimodal catalyst system that is characterized by an inverse response to alkane(s) concentration. The method comprises changing concentration of the alkane(s) in the reactor by an amount sufficient to effect a measurable change in the melt rheology property value; wherein the bimodal catalyst system is characterized by an inverse response to alkane(s) concentration such that when the alkane(s) concentration is increased, the melt rheology property value of the resulting bimodal polyethylene polymer is decreased, and when the alkane(s) concentration is decreased, the melt rheology property value of the resulting bimodal polyethylene polymer is increased.

Zirconocene-titanocene catalyst system

A method for monitoring a chromatograph used to control production of a chemical product. The method involves sampling a chemical mixture of chemical components used during the production to form the chemical product, measuring the composition of the sample with a chromatograph and adjusting the amount of the chemical components based on the measured composition. The method also involves measuring actual parameters of the sample with at least one gauge, determining expected parameters of the sample based on the measured composition and the measured actual parameters using an equation-of-state, and detecting a fault in the chromatograph by comparing the expected parameters with the actual parameters.

A linear low density polyethylene composition suitable for injection molding applications comprising less than or equal to 100 percent by weight of the units derived from ethylene, less than 35 percent by weight of units derived from one or more &#x3b1;-olefin comonomers, and characterized by its density, molecular weight distribution (M/M), a melt index (I), a molecular weight distribution (M/M), vinyl unsaturation, and zero shear viscosity ratio (ZSVR). The linear low density polyethylene composition exhibits low hexane extractable levels.

Polyolefin compositions and uses thereof

A process for the polymerization of olefin monomers comprising contacting ethylene or a mixture of ethylene and one or more C&#x3b1; olefins with a catalyst composition comprising one or more Group 3-10 transition metal containing, Ziegler-Natta, procatalyst compounds; one or more alkylaluminum cocatalyts; and one or more polymerization control agents, said process being characterized in that at least one such polymerization control agent is an alkyl or aryl, ester of an aliphatic or aromatic (poly)carboxylic acid optionally containing one or more substituents comprising a Group 13, 14, 15, or 16 heteroatom.
