    摘要: A molded body contains foamed pellets, containing a composition (M1) containing a thermoplastic elastomer (TPE-1), having a ratio of average surface area to average volume of the pellets (A/V) determined according to method-example 1 and 2 in a range of from 1.4 to 3.0. A process for preparing the molded body involves providing the foamed pellets comprising the composition (M1), and fusing the foamed pellets to obtain the molded body. A molded body obtained or obtainable by the process is useful in furniture, seating, cushioning, car wheels or parts of car wheels, toys, animal toys, tires or parts of a tire, saddles, balls and sports equipment, sports mats, or as floor covering or wall paneling, especially for sports surfaces, track and field surfaces, sports halls, children's playgrounds, and pathways.

    摘要: Molded articles contain a foam composed of a thermoplastic elastotner (TPE-1). The foam has a storage modulus (G modulus) at 25° C. and 1 Hz within the range from 0.01 to 0.5 MPa, a molding density within the range from 20 to 400 kg/m3, and a comfort factor of greater than 4. A process produces molded articles of this kind, and the molded article can be used for producing floors, mattresses, seating furniture, bicycle saddles, car seats, motorcycle seats, components of a shoe, shoe inserts, packaging, shock absorbers, protectors, fall protection mats, elastic insulating material, or sealing material.

    摘要: A process can be used for producing a thermoplastic polyurethane, where the process at least involves converting at least one isocyanate composition and a polyol composition, to obtain a prepolymer having isocyanate groups, and reacting the resulting prepolymer with at least one chain extender. The at least one isocyanate composition contains an isocyanate selected from naphthylene 1,5-diisocyanate (NDI), diphenylmethane 4,4′-diisocyanate (MDI), p-phenyl diisocyanate (PPDI), o-tolidine diisocyanate (TODI), ethylene diphenyl diisocyanate (EDI), or mixtures thereof. The polyol composition contains a polytetrahydrofuran or a derivative thereof. A thermoplastic polyurethane obtained or obtainable by such a process is useful, and a foamed pellet material can be produced containing such a thermoplastic polyurethane. The foamed pellet material of the invention can be used for production of a molded article.

    摘要: A block copolymer contains at least a block (P1) and a block (P2). The block (P1) is obtained or obtainable by reaction of a triblock copolymer having the structure A-B-A′, where block B is selected from polyethers or polyesters and blocks A and A′ are identical or different, and at least one polymer (PM) selected from polyesters and polyethers. The block (P2) is selected from polyamides and polyesters. A process can be used for producing the inventive block copolymer, a shaped article can be made containing the inventive block copolymer, and the inventive block copolymer can be used for producing a shaped article.
