Abstract: Polymer blend compositions having an advantageous combination of low temperature toughness, solvent resistance, scratch resistance, paintability and elevated temperature resistance comprise from about 20 to about 65 weight percent of a rubber modified monovinylidene aromatic/ethylenically unsaturated nitrile/N-arylmaleimide copolymer and from about 35 to about 80 weight percent of certain selected polyester-based elastomeric thermoplastic polyurethane ingredients. The resulting polymer blend compositions are especially well suited for use in the preparation of molded articles or thermoformed sheet materials intended for use in relatively low temperature environments including, for example, in various motor vehicle and/or recreational vehicle applications, as freezer and refrigerator liners, snow removal equipment housings or accessories, and the like.

Abstract: Polymer blend compositions having an advantageous combination of low temperature toughness, solvent resistance, scratch resistance and paintability comprise from about 19 to about 64 weight percent of a mass, solution, mass/suspension or mass/solution polymerized rubber modified monovinylidene aromatic/ethylenically unsaturated nitrile polymer; from about 35 to about 80 weight percent of certain selected polyester-based elastomeric thermoplastic polyurethane ingredients; and from about 1 to about 30 weight percent of a relatively high rubber content emulsion polymerized rubber modified graft copolymer ingredient. The resulting polymer blend compositions are especially well suited for use in the preparation of molded articles intended for use in relatively low temperature environments including, for example, in various motor vehicle and/or recreational vehicle applications, as freezer and refrigerator liners, snow removal equipment housings or accessories, and the like.

Abstract: Articles molded from oxymethylene polymer molding compositions of the present invention exhibit enhanced impact strength properties, especially at low temperatures such as -20.degree. F. It has now been found that the impact strength of articles molded from oxymethylene polymer molding compositions may be improved when the compositions include an elastomeric polyurethane, which is the reaction product of:(i) 4,4'-methylenebis(phenyl isocyanate),(ii) polyoxytetramethylene glycol having a molecular weight within the range of about 1500 to about 3000, and(iii) at least one diol extender selected from the group consisting of aliphatic straight chain diols having from 2 to about 6 carbon atoms, bis(2-hydroxy-ethyl) ether of hydroquinone, and bis(2-hydroxy-ethyl) ether of resorcinol.

Abstract: A thermoplastic elastomeric, uncured or partially cured, composition of EPDM, polypropylene, extender oil and inorganic filler useful for making electrical cords and fittings.
