In various embodiments, a polyethylene formulation has a density of greater than 0.940 g/cmwhen measured according to ASTM D792, and a high load melt index (I) of 1.0 g/10 min to 10.0 g/10 min when measured according to ASTM D1238 at 190&#xb0; C. and a 21.6 kg load. Moreover, the polyethylene formulation has a peak molecular weight (M) of less than 50,000 g/mol, a number average molecular weight (M) of less than 30,000 g/mol, and a weight fraction (w1) of molecular weight (MW) less than 10,000 g/mol of less than or equal to 10.5 wt %, as determined by Gel Permeation Chromatography (GPC). Articles made from the polyethylene formulation, such as articles made by blow molding processes are also provided.

Polyethylene formulations for large part blow molding applications

The present disclosure provides compositions, films and articles containing a random propylene/ethylene copolymer and a substituted phenylene aromatic diester. Polymerization with an improved catalyst system increases the amount of ethylene incorporated into the random propylene/ethylene copolymer backbone which results in improved thermal properties, improved optical properties, and improved heat seal properties.

Propylene/ethylene copolymer film for heat seal

A high density, high polydispersity polyethylene having improved properties, and a process of producing same.

Bimodal polyethylene resins

An ethylene/1-hexene copolymer has a density from 0.9541 to 0.9600 gram per cubic centimeter (g/cm), a molecular mass dispersity (D=M/M) from greater than 2.0 to 3.5; and a Z-average molecular weight (Mz) from 120,000 to 240,000 grams per mole (g/mol). Methods of making and using same. Articles containing same.

Ethylene/1-hexene copolymer

Methods of making polyethylene resins are provided. More particularly methods of modifying the melt flow ratio and swell characteristics of polyethylene resins are provided.

Methods of modifying the melt flow ratio and/or swell of polyethylene resins

Propylene impact copolymers (ICPs) are provided which comprise: (a) a matrix phase which comprises from 60 to 95 weight % of a polypropylene polymer containing from 0 to 6 mole % of units derived from one or more alpha-olefins other than propylene, and (b) a dispersed phase which comprises from 5 to 40 weight % of a copolymer derived from a first comonomer which can be either propylene or ethylene together with a second alpha-olefin comonomer. The ICP is further characterized by having a beta/alpha ratio less than or equal to 1.1. The ICPs of the present invention are particularly well suited for applications requiring clear, tough polymers such as thin walled injection molded articles for frozen food packaging applications.

Propylene impact copolymers having good optical properties

The present invention generally relates to composite laminates and uses thereof in articles in need of protection from mechanical damage and water or oxygen based degradation.

Composite laminates and uses thereof

Polyesteramides prepared from decreased perfection diamide diester monomers. The polymers exhibit improved physical properties.

Copolyesteramides with decreased perfection of the amide sequence

The present disclosure is directed to random propylene/&#x3b1;-olefin compositions, articles, and processes for producing the same. The present compositions contain a random copolymer of propylene and &#x3b1;-olefin. Polymerization with an improved catalyst composition increases the molecular weight distribution of the copolymer and increases the randomness of comonomer distribution to yield random propylene/&#x3b1;-olefin copolymers with improved stiffness and/or improved optical properties.

Random propylene copolymer compositions, articles and process

The present invention relates to new (meth)acrylate compositions, their preparation and their use in ultraviolet light curable applications such as coatings, inks and adhesives.

Reactive (meth)acrylate monomer compositions and preparation and use thereof
