A polyethylene composition particularly suited for producing blow-molded hollow articles, having the following features:

Polyethylene composition for blow molding having an improved swell behavior

A process for producing a low density polyethylene with modified melt flow index, comprising subjecting to thermal visbreaking a precursor polyethylene (I) comprising 35% by weight or more of LDPE.

Process for modifiyng the melt flow index of low density polyethylene

A process for producing a low density polyethylene with modified melt flow index, comprising subjecting to thermal visbreaking a precursor polyethylene (I) comprising 35% by weight or more of LDPE and blending the so obtained intermediate polyethylene product (II) with an additional polyethylene (III).

A polyethylene composition for producing blown films, made from or containing an ethylene homopolymer or copolymer A) and an ethylene copolymer B) having a MIE value lower than the MIE value of A), the composition having the following features:

Polyethylene composition for films

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 polyethylene composition having the following features:

A polyethylene composition having the following features: The polyethylene composition can be used to produce pipes and films.

Polyethylene composition having high mechanical properties and processability

The present disclosure relates to pipes comprising bimodal high molecular weight high density polyethylene which has been extruded in the presence of one or more organic peroxides that are present in an amount ranging from 30 ppm to 200 ppm. The pipe has an improved long-term hydrostatic strength. Also provided are methods for preparing pipes having these characteristics.

Low-sag polyethylene pipes and methods thereof

Polyethylene composition for injection molding with a beneficial balance of environmental stress cracking resistance and impact resistance in combination with low warpage and beneficial processing behavior, said composition having the following features:

Polyethylene composition for injection moulding

Disclosed is a process for making a linear low density polyethylene (LLDPE) having low gels. The process comprises copolymerizing ethylene with one or more C&#x3b1;-olefins to produce an LLDPE resin which has a gel defect area less than 25 ppm. The copolymerization is performed in the presence of a Ziegler-Natta catalyst which comprises an MgClsupport, a Ti(IV) complex, and a cyclic ether as an internal electron donor. The Ziegler-Natta catalyst has an Mg/Ti molar ratio greater than or equal to 7.

Preparation of LLDPE resins and films having low gels

A polyethylene composition made from or containing a polyethylene, having the following features:

Polyethylene composition having high stress cracking resistance

High clarity polyethylene films
