Disclosed are ionomer compositions neutralized by a combination of cesium and potassium that have antistatic properties. Also disclosed are articles, including laminates and monolayer or multilayer structures comprising such compositions to which neither powders nor dusts easily adhere electrostatically.

Antistatic ionomer composition and articles therewith

A composition is disclosed which comprises a mixture of a poly(trimethylene terephthalate) polymer composition, a nucleating agent, and an ethylene copolymer. Also disclosed in a method for reducing the melt viscosity of nucleated poly(trimethylene terephthalate) polymer composition.

Toughened poly(trimethylene terephthalate) composition with reduced melt viscosity

A curable thermoplastic elastomeric blend comprising: (a) from 15 to 60 weight percent of a polyalkylene phthalate polyester polymer or copolymer and; (b) from 40 to 85 weight percent of a poly(meth)acrylate or polyethylene/alkyl (meth)acrylate rubber in combination with an effective amount of peroxide free-radical initiator and an organic multiolefinic coagent to cross-link which upon extrusion or injection molding dynamically cross-link producing a melt processible thermoplastic elastomeric composition having a polyalkylene phthalate polyester polymer or copolymer continuous phase and of a cross-linked polyacrylate or polyethylene/acrylate rubber dispersed phase. Such compositions are useful in the manufacture of rubber parts having excellent resistance to lubricating oils and greases.

Curable thermoplastic elastomeric blend, method of manufacture, and use thereof

Disclosed are soft polymer compositions comprising an ethylene/alkyl (meth)acrylate copolymer and a crystalline polyolefin, such as polypropylene homopolymers or polypropylene copolymers, wherein the ethylene/alkyl (meth)acrylate copolymer has a higher melt viscosity than the polyolefin. Also disclosed are such compositions modified by materials that improve the scratch-and-mar properties of the blends, the preparation and use of these compositions in such processes as extrusion and injection molding, and articles made from these compositions.

Soft polymer compositions having improved high temperature properties

Disclosed are polyamide potassium ionomer polyol compositions that have antistatic properties. Also disclosed are articles, including laminates and monolayer or multilayer structures comprising such compositions to which neither powders nor dusts easily adhere electrostatically.

Antistatic polyamide composition and articles therewith

Disclosed are films, tapes, and melt-spun fibers comprising or prepared from a composition comprising (a) at least one polyamide polymer; and (b) from about 0.1 to 20 weight % of at least one ethylene copolymer such as ethylene/vinyl acetate dipolymers, ethylene/vinyl acetate terpolymers, ethylene/alkyl (meth)acrylate dipolymers, ethylene/alkyl (meth)acrylate terpolymers, functionalized ethylene copolymers, ethylene/acid copolymers, and salts thereof. The films, tapes and fibers exhibit improved tensile properties such as tensile strength and elongation at break compared to nonmodified polyamide compositions. Also disclosed are nonwoven textiles comprising or prepared from the oriented melt-spun fibers.
