    Abstract: The invention concerns a method of inscribing by means of high-energy radiation mouldings based on thermoplastic polymers A) or mixtures of these polymers with up to 70 wt %, relative to the total weight of the components, of further additives and processing aids. The invention is characterized in that a vinylaromatic polymer B) is used as additive for improving inscribability, this polymer having been modified by the incorporation of at least one functional group selected from the series comprising carbonyl, carboxylic acid, acid anhydride, acid amide, acid imide, carboxylic acid ester, carboxylate, amino, hydroxyl, epoxy, oxazolin, urethane, urea, lactam or benzyl halide groups.

    Abstract: REINFORCED CELLULAR OR NONCELLULAR POLYURETHANE MOLDED PARTS Reinforced cellular or noncellular molded polyurethane parts are prepared by heating a mixture of reinforcing materials and a heat-curable composition of polyisocyanates and polyols in an open or closed mold, said composition being storage-stable at room temperature and containing, optionally, auxiliaries and additives. In said composition, the polyisocyanate is dispersed in the form of discreet particles having particle diameters from 0.1 to 150 .mu.m in the polyol and the polyisocyanate particles are deactivated on their surfaces such that from 0.01 to 20 equivalent percent of the total available isocyanate groups are deactivated and such that the ratio of free isocyanate groups to hydroxyl groups is from 0.7:1 to 2.5:1. The polyurethane molded parts are suitable for use as self-supporting trim parts, reinforcement parts, or molded parts for various applications.

    Abstract: The invention relates to compositions which are storage-stable at room temperature and which can be heat-cured to form molded parts having polyurethane, polyurea, and polyisocyanurate groups, said composition containing (a) one or more polyols having a molecular weight of from 400 to 10,000 and a functionality of from 2 to 8, (b) at least one polyfunctional compound having a molecular weight of 62 to 400 and being selected from the group consisting of aliphatic hydroxyl compound, cycloaliphatic hydroxyl compounds, aromatic amino compounds, or mixtures thereof, and (c) an organic polyisocyanate which is present in the form of discrete particles, which are deactivated on their surfaces and are dispersed in the liquid component, and depending on the product needs, (d) catalysts, (e) blowing agents, (f) reinforcing materials, and (g) auxiliaries and additives, The single-component systems are used for the preparation of cellular or noncellular, optionally reinforced polyurethane, polyurea, and/or polyisocyanurate group-containing molded parts.
