Abstract: A composition contains thermoplastic polyurethane, which is the reaction product of a pentamethylene diisocyanate, a polycarbonate diol, and a chain extender. The composition is useful for producing articles. A production process for producing a filled composition involves adding glass to the composition. Articles can be derived from the composition and the filled composition.

Abstract: Foamed pellets contain a block copolymer. The block copolymer is obtained or obtainable by a process involving the reaction of an aromatic polyester (PE-1) with an isocyanate composition (IC), containing at least one diisocyanate, and with a polyol composition (PC). The polyol composition (PC) contains at least one aliphatic polyol (P1) having a number-average molecular weight ≥500 g/mol. A process can be used for the production of such foamed pellets. The foamed pellets can be used for the production of a molded body.

Abstract: A thermoplastic polyurethane can be obtained by a process involving a reaction of a thermoplastic polyester (PE-1) with a diamine (D1), to obtain a composition (Z1) containing an amide (PA-1), and a reaction of the obtained composition (Z1) with an isocyanate composition (I1), containing at least one polyisocyanate, and a polyol composition (P1). The diamine (D1) has a molecular weight in the range from 50 g/mol to 700 g/mol. A process can produce such a thermoplastic polyurethane, and shaped articles can be made containing the thermoplastic polyurethane.
