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 blow-molded hollow articles, having the following features:

Polyethylene composition having environmental stress cracking resistance

Polethylene composition having high swell ratio

A polyethylene composition for producing blow-molded hollow articles, having the following features: 1) a density from 0.945 to 0.958 g/cm, determined according to ISO 1183 at 23&#xb0; C.; 2) a ratio MIF/MI10 from 2 to 10; 3) a &#x3b7;from 200,000 to 800,000 Pa&#xb7;s; 4) a LCBI equal to or lower than 0.80; and 5) a ratio (&#x3b7;/1000)/LCBI equal to or greater than 350.

Polyethylene composition having high swell ratio, fnct and impact resistance

Polyethylene composition for blow molding having high stress cracking resistance

Polyethylene composition for blow molding having high swell ratio and impact resistance

Novel polyethylenes having defined molecular weight distribution and LCB structure are devised, for films or moldings.

Polyethylene composition and finished products made thereof

Embodiments of the present disclosure relate to a method of preparing polyethylene compositions comprising polymerizing ethylene in a first gas-phase reactor and polymerizing ethylene in a second gas-phase reactor in the presence of hydrogen; wherein at least one of the first or second gas-phase reactors comprises a first and second polymerization zone; wherein a hydrogen pressure of the first and second polymerization zones are different such that at least a portion of the second ethylene cycles through the first and second polymerization zones and a gas mixture of each polymerization zone is partially or totally prevented from entering the other zone.

Polyethylene processes and compositions thereof

A novel polyethylene composition is described. The composition is suitable for manufacturing especially stretched bands or tapes, also coined raffia in the art.
