Thermoplastic polyurethanes are obtainable by reacting (a) isocyanates with (b1) polyesterdiols having a melting point greater than 150-C, (b2) polyetherdiols and/or polyesterdiols, each having a melting point of less than 150-C and a molecular weight of from 501 to 8 000 g/mol, and, if required, (c) diols having a molecular weight of from 62 to 500 g/mol.

Thermoplastic polyurethanes

Thermoplastic polyurethane (i) comprising from 20% by weight to 70% by weight of isocyanate dissolved in the thermoplastic polyurethane, based on the total weight of the thermoplastic polyurethane (i) comprising the isocyanates.

Isocyanate-containing thermoplastic polyurethane

Thermoplastic polyurethanes are obtainable by reacting (a) isocyanates with (b1) polyesterdiols having a melting point greater than 150&#xb0; C., (b2) polyetherdiols and/or polyesterdiols, each having a melting point of less than 150&#xb0; C. and a molecular weight of from 501 to 8000 g/mol, and, if required, (c) diols having a molecular weight of from 62 to 500 g/mol.

The invention relates to thermoplastic polyurethane with a Shore hardness of 45A to 80A, a tensile strength, according to DIN 53504, higher than 5 Mpa, a tear strength, according to DIN 53515 higher than 30 N/mm and an abrasion according to DIN 53516 of less than 250 mm .

Conductive nylon molding materials

A process for the preparation of high-impact nylon molding materials, containing 30-88% by weight of a thermoplastic nylon, 10-50% by weight of an organosilane-coated silicate reinforcing filler, 0.1-5% by weight of a polyurethane ionomer, 2-30% by weight of a carboxyl-containing thermoplastic elastomer and, where appropriate, effective amounts of conventional additives, by mixing the silicate filler, coated with an organosilane and a polyurethane ionomer, with the thermoplastic elastomer and the nylon at above the melting point of the nylon, wherein, in a first stage, the silicate filler coated with an organosilane and a polyurethane ionomer is mixed with the nylon at above the melting point of the latter, and in a second stage the thermoplastic elastomer is finely dispersed in the filler-containing nylon at above the melting point of the latter.

Preparation of high-impact nylon molding materials

Fibrids are prepared by introducing a solution of a polymer into a liquid precipitation medium while exposing it to shearing forces. A poly(amide-imide) resin solution is admixed with a solvent which is miscible with the resin solvent but which is a non-solvent for the resin itself.

Manufacture of fibrids from poly(amide-imide) resins

The manufacture of paper-like and textile-like sheet materials by the use of fibrids which have been obtained by dissolving poly(amide-imide) resins in an organic solvent, mixing the resulting solution with a liquid which is a non-solvent for the polymer and introducing the resulting solution into a liquid precipitation medium while exposing it to shearing forces.
