Abstract: A graft macromer, comprising the reaction product of at least one macromer being at least one molecule which comprises in its structure one or more hydroxyl-terminated polyether and/or polyester chains, with at least one grafting compound which comprises in its structure at least one at least monoalkoxylated or at least monohalogenated silyl group and at least one alkyl, cycloalkyl or aryl containing group which is reactive towards the hydroxyl group of the macromer, is used for dispersing e.g. SiO2 in a polyol.

Abstract: The present invention relates to a process for producing a polyurethane, comprising the reaction of a polyol composition (PZ) comprising a polyol (P1) with a polyisocyanate composition (PIZ-1) comprising a polyisocyanate (I1) to obtain a hydroxyl-terminated prepolymer (PP1) and the reaction of the prepolymer (PP1) obtained with a polyisocyanate composition (PIZ-2) comprising a polyisocyanate (I2) and at least one chain extender (K1) to obtain a polyurethane (PU1), wherein the molar ratio of the OH groups in the components of the polyol composition (PZ) to the isocyanate groups in the components of the polyisocyanate composition (PIZ-1) in the reaction in step (i) is in the range from 1.3:1 to 10:1. The present invention further relates to polyurethanes obtainable or obtained by such a process, and to the use of the polyurethanes for production of shaped bodies, adhesives, coatings, hoses, films, nonwoven articles or fibers.

Abstract: A preparation contains a thermoplastic polyisocyanate polyaddition product (TPPP), where the thermoplastic polyisocyanate polyaddition product (TPPP) is obtained by reacting a polyisocyanate, a compound reactive with isocyanate, and water, in the presence of a defoamer containing a polyalphaolefin. Respective production processes as well as the use and devices derived from that preparation are useful.

Abstract: A method for producing a shaped body, containing: producing the shaped body from a composition by a powder-based layer construction process, wherein the composition contains a thermoplastic polyurethane, obtained by reacting a polyisocyanate composition and a polyol composition, the thermoplastic polyurethane is solid at least in a temperature region below 50° C. and has end groups selected from the group consisting of first end groups and second end groups, wherein the first end groups are optionally eliminated at a first temperature, and the second end groups are optionally eliminated at a second temperature, to form reactive groups on the thermoplastic polyurethane that optionally enter into a reaction with functional groups of the thermoplastic polyurethane or functional groups of a further component of the composition, and wherein the first temperature and the second temperature are each greater than or equal to 60° C.
