Abstract

This invention relates to a process for the preparation of single-layered or multilayered molded articles from particles of polyisocyanate-polyaddition products comprising thermoplastically shaping under pressure (i) polyisocyanate-polyaddition products prepared by reacting (a) aliphatic, cycloaliphatic, or aromatic polyisocyanates;
(b) compounds having a molecular weight of from about 1800 to about 12,000 and containing, on statistical average, at least 2.5 isocyanate-reactive groups;
(c) optionally, diamines having a molecular weight of from about 108 to about 400 with two primary and/or secondary aromatically bound amino groups; and (d) optionally, alkane polyols, cycloalkane polyols, alkane polyamines, and/or cycloalkane polyamines having a molecular weight of from about 60 to about 1799 and containing ether groups;
with the proviso that at least one of components (c) or (d) has a molecular weight of from about 60 to about 400 and comprises at least 5% by weight based on the weight of component (b);
in the presence of (ii) one or more processing auxiliaries selected from solvents that swell the surface of the products, compounds that can react with the products, radical formers, and other thermoplastic materials.
This invention also relates to the molded articles prepared by the process of the invention.
