Butene-1 polymer composition having a high melt flow rate

The present disclosure generally relates to ethylene alpha-olefin copolymers and methods of making ethylene alpha-olefin copolymers. The ethylene alpha-olefin copolymers may have a density of about 0.915 g/mL to about 0.918 g/mL, a rheological polydispersity index greater than 0.8, a melt index of about 0.4 dg/10 min to about 2.0 dg/10 min, and/or a CEF Tof 84&#xb0; C. or less. The ethylene alpha-olefin copolymers may be made by combining an ethylene monomer and one or more alpha-olefin monomers in the presence of a catalyst, such as a Ziegler-Natta catalyst.

Ethylene alpha-olefin copolymers and methods

A gas-phase process for the homopolymerization or copolymerization of olefins carried out in the presence of a catalyst system formed by a contacting, in a liquid hydrocarbon and in the presence of hydrogen, (a) a solid catalyst component comprising Ti, Mg, and Cl, and optionally an internal electron donor compound, (b) an aluminum alkyl compound and optionally (c) an external donor compound.

Process for the polymerization of olefins

A method for feeding an antistatic compound to a polymerization reactor comprising the steps of: a) dispersing, under mixing conditions, a catalyst powder and an antistatic compound in an oil, so as to form a suspension of catalyst powder and antistatic compound in said oil; b) successively adding, under mixing conditions, a molten thickening agent to said suspension from step a), while maintaining said suspension at a temperature such that said thickening agent solidifies on contact with said suspension; c) transferring the product obtained from b) to a polymerization reactor.

Method for feeding an antistatic compound to a polymerization reactor

The present technology relates to a method of introducing a supported antistatic compound that does not comprise a transition-metal-based catalyst component for use in an olefin polymerization reactor. In some embodiments, the methods disclosed herein avoid the formation of polymer agglomerates in the reactor and minimize potentially negative effects on catalyst yield.
