    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.

    摘要: A process for producing a block copolymer may involve reacting at least one aromatic polyester having a melting point in the range from 160 to 350° C. with at least one second compound selected from diamines and diols at temperatures greater than 160° C. to obtain a mixture; and heating the mixture at a temperature in the range from 100° C. to 300° C. for from 1 to 240 hours to obtain a block copolymer, wherein in the reacting, the second compound is employed in an amount of 0.02 to 0.3 mol per mol of ester bond in the polyester. Block copolymers may be obtained by such a process and used for producing extruded, injection molded and pressed articles and also foams, foam particles, shoe soles, cable sheaths, hoses, profiles, drive belts, fibers, nonwovens, films, moldings, plugs, housings, damping elements for the electronic/automotive industry, mechanical engineering, 3-D printing, medicine, or consumer goods.

    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.
