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.

Abstract: A sound insulation device contains at least one rigid support element and at least one elastic membrane element. The rigid support element contains at least one support grid containing a plurality of cells. The elastic membrane element is arranged on the support grid. The sound insulation device is configured to block at least partially acoustic energy transmission at a frequency range of 60 Hz to 500 Hz. The sound insulation device exhibits a negative effective mass below a resonance frequency, where the resonance frequency is given by: ω 0 = 4 π δ A E ρ ( 1 - ϑ 2 ) , where A is a pore size of the support grid spun by the membrane element, δ is a thickness of the membrane element, E is an elastic modulus of the membrane element, ρ is a density of the membrane element, and ϑ is a Poisson ratio of the membrane element. The elastic modulus E of the membrane element is ≥8 MPa.
