    Abstract: Polyurethane moulding compositions which can be melt processed in the form of sintering powders suitable for the preparation of grained sintered films and which are prepared exclusively from linear aliphatic components are described. The polyol component is composed of 30 to 80 parts by weight of an aliphatic polycarbonate diol with an average molecular weight {overscore (M)}n of 1000 to 2200 and 70 to 20 parts by weight of a polybutane diol adipate and/or a polycaprolactone diol with an average molecular weight {overscore (M)}n of 1000 to 2400. Moreover, the mixture contains 1,6-hexamethylene diisocyanate in an equivalence ratio of 2.3:1.0 to 6.2:1.0, based on the polyol mixture and butane-1,4-diol as chain extender, the equivalence ratio of the butane-1,4-diol based on the poly mixture being 1.3:1.0 to 5.2:1.0.

    Abstract: The invention relates to a process for producing fiber composite moldings comprising(i) a thermally crosslinkable fiber composite layer as backing layer, and (ii) a thermoplastic fiber composite layer as overlayer, by mutually superposing the fiber composite layer (i) comprising a thermally crosslinkable binder in the unhardened state and the thermoplastic overlayer (ii), and, in a molding press, converting them to the desired form and thermally crosslinking the same, which comprises a higher temperature of the first contact area of the molding press, where this has contact with the backing layer, than of the second contact area of the molding press, where this is in contact with the overlayer.
