摘要：A process for the production of moulded articles or films based onpolyisocyanate polyaddition products of a density of at least 0.8 g/cm<3> by

thermoplastic moulding at temperatures in excess of 20 DEG C and at pressures in excessof 1 bar, the products being used as polyisocyanate polyaddition products being thosebased on a) (cyclo)aliphatic polyisocyanates, b) compounds in the molecular weight range1,800 to 12,000 which have on statistical average at least 2.5 groups which react toisocyanate groups, optionally c) aromatic diamines of the molecular weight range 108 to400, as well as optionally d) (cyclo)alkane polyols and/or (cyclo)alkane polyamides of themolecular weight range 60 to 1,799, optionally having ether groups, as well as optionallytogether with use of e) the auxiliaries and additives known per se from polyurethanechemistry, the moulded articles being produced with retention of an isocyanatecharacteristic number of 60 to 140, and at least one of the components c) and/or d)being included in a quantity such that the total quantity of the components c) and/or d)amounts to at least 5% by weight, referred to the weight of the component b).
