Expandable-polymer-particle material comprising at least one thermoplastic polyurethane (TPU) with Vicat softening point (in accordance with ISO 306/ASO) below 80&#xb0; C. and from 5 to 95% by weight of at least one polymer obtainable via free-radical polymerization, based on the entirety of TPU and of the polymer obtainable via free-radical polymerization, where the polymer obtainable via free-radical polymerization has been bonded to the TPU in a manner that gives a comb polymer, graft polymer, or copolymer, is suitable for the production of moldings, in particular for use as insulation material.

Polyurethane-based expandable polymer particles

The invention relates to a method for producing hollow bodies having freely displaceable particles enclosed in the hollow body, wherein a) a gel-forming liquid in which the particles are suspended is brought into a cross-linking bath, b) the gel cores that form are isolated, c) the cores are coated with a composition comprising sinterable material and a binder, and d) the coated cores are subjected to a heat treatment wherein the gel and the binder are expunged and the sinterable material is sintered into a closed shell. The gel forming material is, for example, sodium alginate, and the cross-linking bath comprises calcium ions. The particles are selected, for example, from ZrO, AlO, TiO, and SiOor mixtures thereof. The sinterable material is, for example, a metal powder such as carbonyl iron powder.

Method for producing hollow bodies having enclosed freely displaceable particles

The invention relates to elastic expanded polymer foams and also a process for producing expanded polymer foams by sintering a mixture comprising foam particles P1 and P2 composed of different thermoplastic polymers or polymer blends, wherein the foam particles P1 are obtained by prefoaming expandable, thermoplastic polymer particles comprising
