Abstract: Disclosed is a composition comprising, consisting essentially of, consisting of, or produced from polyvinyl chloride, filler, and an impact strength-retaining amount of a modifier wherein the modifier includes is or an ethylene copolymer, an acid anhydride- or acid monoester-modified polyolefin, or combinations thereof. Also disclosed is a process comprising combining an impact strength-retaining amount of a modifier to a blend that comprises or is produced by combining a rigid PVC and one or more fillers. The combining is carried out under a condition sufficient to prevent or minimize the reduction of impact strength of the blend, to reduce the molten viscosity of the blend, or to minimize the loss in stiffness (flexural modulus) of the blend, in comparison to the unmodified blend.

Also disclosed is a process which comprises combining the modifier to a blend that comprises or is produced by combining rigid PVC and one or more fillers. Further disclosed are articles comprising or produced from the composition.

Abstract: Disclosed is a composition comprising, consisting essentially of, consisting of, or produced from polyvinyl chloride, filler, and an impact strength-retaining amount of an elastomer wherein the modifier is or includes an ethylene copolymer, or acid anhydride- or acid monoester-modified polyolefin, or combinations thereof. Also disclosed is a process comprising combining an impact strength-retaining amount of an elastomer to a blend that comprises or is produced by combining a rigid PVC formulation and one or more fillers. The combining is carried out under a condition sufficient to prevent or minimize the reduction of impact strength of the blend, to reduce the molten viscosity of the blend, or to minimize the loss in stiffness (flexural modulus) of the blend, in comparison to the unmodified blend.

Abstract: A composition and an article made from the composition are disclosed. The composition comprises, or is produced from, an ionomer, a polyamide, and one or more esters of montanic acid. The article includes film, sheet, filament, tape, molded part, thermoformed product, and container for food or non-food packaging, or combinations of two or more thereof.

Abstract: Disclosed are conductive polymeric materials comprising a resin-based structural material loaded with micron conductive fibers and/or micron conductive powders or to provide a conductive thermoplastic composition rather than an insulator. Also disclosed are antennas comprising the conductive thermoplastic compositions and methods for their fabrication.

Abstract: An ionomer/polyamide blend with improved flow (e.g., lower viscosity) can be achieved while simultaneously maintaining or improving physical properties such as low temperature Izod impact resistance by the addition of low molecular weight ethylene/acrylic acid copolymer (e.g., so-called acid wax polymer derived from copolymerizing at least 5 weight percent and preferably greater than 9 weight percent acrylic acid and/or methacrylic acid with ethylene and having a melt index, ASTM D1238, preferably greater than 900 dg/min and most preferably greater than 5,000 dg/min). Optionally, the blends can further contain additives such as very low density polyethylene (VLDPE), ethylene propylene elastomer (EPR), ethylene propylene diene monomer elastomer (EPDM), corresponding maleic anhydride grafted elastomers (MAN-g-VLDPE; MAN-g-EPR; and MAN-g-EPDM), or mixtures thereof.

Abstract: An ionomer/high density polyethylene (HDPE) blend with improved flow (e.g., lower viscosity) can be achieved without significantly degrading physical properties such as impact resistance and tensile strength by the addition of low molecular weight ethylene/acrylic acid copolymer (e.g., so-called acid wax polymer derived from copolymerizing at least 5 weight percent and preferably greater than 9 weight percent acrylic acid and/or methacrylic acid with ethylene and having a melt index, ASTM D1238, preferably greater than 900 dg/min and preferably greater than 5,000 dg/min). The blend may further have for every one hundred parts by weight of ionomer/high density polyethylene blend from one to twenty parts by weight polyethylene modified with from 0.2 to 5.0 weight percent maleic anhydride comonomer as an impact resistance additive.

Abstract: A maleic anhydride modified ethylene polymer/ionomer/high density polyethylene blend having improved impact resistance (e.g., increased low temperature Izod impact) can be achieved by the addition of a maleic anhydride grafted high ethylene derived polymer (e.g., MAN-g-HDPE, MAN-g-VLDPE, MAN-g-EPR, MAN-g-EPDM, and the like) to ionomer and high density polyethylene during blending. The blends exhibiting improved impact resistance characteristics according to the instant invention are particularly useful in the manufacture of automotive parts, panels and the like having a “class A” surface.

Abstract: The present invention relates to bonding resins having excellent adhesion to polar polymers, particularly ionomers, acid copolymers and ethylene vinyl alcohol copolymer. These resins preferably contain: 1) an ethylene polymer or copolymer (ungrafted, grafted or partially grafted); 2) a grafted elastomer; and 3) optionally, an ethylene alpha olefin copolymer which is wholly or partially grafted. Preferred grafting comonomers include maleic anhydride and derivatives thereof.
