The present invention relates to a process for producing a flexible polyurethane foam thermally recyclable by fusion, and to hybrid materials made of flexible polyurethane foam and compact thermoplastic elastomer and/or expanded thermoplastic polyurethane.

Flexible polyurethane foams

A polyurethane, in particular a thermoplastic polyurethane, is obtainable or obtained by reacting at least a polyisocyanate composition and a polyol composition. The polyol composition contains at least one polyester diol or polyether diol, having a number-average molecular weight in the range from 500 to 3000 g/mol, and at least one polysiloxane having two terminal isocyanate-reactive functionalities selected from a thio group, a hydroxyl group, and an amino group. A process can be used for preparing this polyurethane, and a molded body containing the polyurethane is useful. Foam beads based on polyurethane can be obtained or obtainable from the polyurethane, and a process can be used for producing foam beads. Corresponding bead foams are useful.

Thermoplastic polyurethane

The present invention relates to a polyurethane, in particular a thermoplastic polyurethane, obtainable or obtained by reacting at least the components (i) to (ii): The invention additionally relates to a process for preparing this polyurethane, to the use thereof, to a molded body comprising the polyurethane. Furthermore, the invention relates to foam beads based on polyurethane, obtained or obtainable from the polyurethane, to a process for producing foam beads and also to bead foams and to the use thereof.

The present invention is concerned with a new macromer for use in polymer polyol dispersions, and also with a process for preparing a new macromer of this kind.

Macromer for use in polymer polyol dispersions, and method for producing such a macromer

The present invention relates to a method of preparing a polyurethane elastomer, said method comprising the step of reacting at least one isocyanate composition (ZI) and one polyol composition (ZP) comprising a poly-&#x3b5;-caprolactone polyol and an &#x3b1;-hydro-&#x3c9;-hydroxy-poly(oxytetramethylene) polyol to obtain an isocyanate-functional prepolymer and the step of reacting the prepolymer obtained as per step (i) with at least one chain extender (KV). The present invention further relates to a polyurethane elastomer obtained or obtainable according to a method of the invention and also to the method of using a polyurethane elastomer according to the invention or a polyurethane elastomer obtained or obtainable according to a method of the invention in the manufacture of a shaped article, especially a damping element, a shock absorber or a stop buffer or part of a shoe or of a shoe sole, for example part of an insert sole or of a midsole.

Low-damping polyurethane elastomer

This invention relates to a stabilizer for polymer polyol production processes, its production and use.

Stabilizer for polymer polyol production processes

This invention relates to a continuous process for making a polymer polyol, the polymer polyol produced according to the said process and its applications.

Process for making a polymer polyol

The present invention relates to a process for producing pipelines with heat-storing properties, in which a) organic polyisocyanate is mixed with b) at least one polymeric compound having at least two isocyanate-reactive hydrogen atoms, c) optionally chain extender and/or crosslinker, d) catalyst, e) wax and f) optionally other assistants and/or additives, to give a first reaction mixture, and the first reaction mixture is applied to a pipe and allowed to react fully to give a first polyurethane layer. The present invention further relates to a pipeline with heat-storing properties obtainable by such a process.

Pipeline with heat-storing properties

The invention relates to particle-comprising polyether alcohols which can be prepared by in-situ polymerization of olefinically unsaturated monomers in a polyether alcohol, wherein the polymerization is carried out in the presence of at least one compound (A) comprising a polysiloxane chain to which at least one polyether chain comprising at least one reactive hydrogen atom and a polyether chain comprising at least one olefinic double bond are bonded.

Particle-comprising polyether alcohols

The present invention relates to a process for preparing polyurea elastomers, in which (a) polyisocyanates are mixed with (b) polyamines, (c) optionally amine chain extenders comprising primary or secondary amine groups, (d) optionally polyols and (e) optionally auxiliaries and additives to form a reaction mixture and cured, where at least one of the components (a) to (d) comprises dispersed filler particles.
