    Abstract: The prodn. of polyurethane (PU) foam comprises reacting (a) polyisocyanate(s); with (b) high-mol. wt. polyol(s) with at least two reactive H atoms, comprising (B1) polyoxyalkylene-polyol(s) with an OH no. of 30-500, obtd. by alkoxylating N,N'-bis(3-aminopropyl)-ethylenediamine, tripropylene-tetramine and/or tetrapropylene-pentamine with alkene oxide(s); and opt. (c) low-mol wt. chain extenders and/or crosslinkers; in the presence of (d) blowing agents. Also claimed are polyols (b1) obtd. as above.

    Abstract: The invention relates to soft, elastic polyurethane sheets, expediently having a thickness of from 0.3 to 3 mm, which are produced by sintering pulverulent thermoplastic polyurethanes having a melt flow index of from 50 to 350 at 190 DEG C under a weight of 212 N, and having a Shore A hardness of from 80 to 98, preferably in the presence of from 0.05 to 1 part by weight of a pulverulent aluminium oxide and/or silica gel per 100 parts by weight of the thermoplastic polyurethane, by means of a heatable mould. The polyurethane sheets are preferably used for coating mouldings for the interior of motor vehicles.
