The present disclosure relates to polymer compositions, articles formed from polymer compositions, methods of making polymer compositions, and methods of making articles including polymer compositions. In at least one embodiment, a composition includes: (1) an ethylene polymer, (2) a vinyl alcohol polymer or a polyamide, and (3) a polar polymer or a grafted polyolefin. A composition of the present disclosure may further include a polypropylene polymer. A polar polymer may be an ethylene-acrylic-acid-copolymer, ethylene acrylate copolymer, a polyvinyl acetate, or combination(s) thereof. In at least one embodiment, a film includes a composition having: (1) an ethylene polymer, (2) a vinyl alcohol polymer or a polyamide, and (3) a polar polymer or a grafted polyolefin.

Polyolefin compositions, articles thereof, and methods thereof

Polymeric coating compositions and articles coated with the polymeric coating compositions are provided. The polymeric coating composition can include an ethylene-based polymer that exhibits desirable melting properties and molecular weight distribution. The polymeric coating composition can provide a thin coating layer on an article while still providing advantageous properties, such as seal strength.

Polymeric coating compositions and articles coated with the same

A process for producing an ethylene copolymer, the process including: (a) contacting ethylene with at least one polar comonomer in the presence of at least one modifier and at least one free radical initiator in a tubular reactor under polymerization conditions including a pressure of from 225 to 270 MPa; (b) injecting the at least one free radical initiator into the reactor at a plurality of reaction zones spaced along the length of the reactor, wherein each reaction zone comprises an inlet and an outlet; (c) maintaining the temperature at the inlet of each reaction zone at 150&#xb0; C. or less, and the temperature at the outlet of each reaction zone is at least 177&#xb0; C.; (d) controlling the modifier flow at a rate of from 0.02 to 0.986 wt % of the copolymer; and (e) recovering the ethylene copolymer from the tubular reactor, is provided.

Process for producing ethylene copolymers

A laminated article comprises a substrate having opposite major surfaces, and a multi-layer lamination composition comprising (i) a base layer and (ii) an adhesion layer bonded to at least one surface of the base layer. The adhesion layer (ii) comprises a propylene copolymer which comprises units derived from propylene and from about 3 to about 25 wt % of units derived from ethylene and/or a Cto Calpha-olefin and which has a melting temperature less than about 105&#xb0; C. and a heat of fusion less than about 75 J/g. The lamination composition is thermally laminated to the substrate such that said adhesion layer (ii) is bonded to at least one major surface of said substrate.

Laminated articles and their production

A polymeric composition that is suitable for use as a film or a coating. The polymeric composition comprises: (a) a first component comprising copolymer derived from ethylene and one or more Cto C&#x3b1;-olefin comonomers. The first component has a density of about 0.911 to about 0.918 g/cm, a compositional distribution breadth index (CDBI) of about 60% to about 85%, a melt index (MI) of about 16.0 to about 30.0 g/10 min, a molecular weight distribution (MWD) of about 1.5 to about 4.0, and a melt index ratio (MIR) of less than about 25; and (b) a second component comprising a low density polyethylene (LDPE). The second component has a g' of about 0.8 to about 0.15 and a MI that is lower than the MI of the first component.

Polyolefin compositions and products made therefrom

A film structure including at least a base layer containing a thermoplastic polymer and at least an outer layer containing a low melting point polymer. Methods of manufacturing the film structure, including the steps of coextruding melts corresponding to the individual layers of the film structure through a die and thereafter: simultaneously biaxially stretching the coextruded film sheet; or sequentially biaxially stretching the coextruded film sheet, wherein the machine-direction orientation (MDO) is performed with a radiant-heated MDO stretcher. An extrusion-coated film structure exhibiting strong bond adhesion, and a method of manufacturing the same are also provided.
