    Abstract: The invention relates to a process for preparing self-releasing, compact or cellular moulded bodies optionally containing reinforcing agents and made of polyisocyanate polyaddition products by reacting a) organic and/or modified organic polyisocyanates with b) at least one compound with at least two reactive hydrogen atoms and a molecular weight of 500 to 9,000 and optionally c) chain extension and/or cross-linking agents in the presence of d) alkyl and/or alkenyl succinic acid monoamides, -monoamides, poly(alkyl succinic acid)- and/or poly(alkenyl succinic acid)-polyamides, -polyimides, -monoamide monoimides, -polyamide imides, -amide polyimides and- polyamide polyimides or mixtures thereof as internal mould release agents, and also in the presence or absence of e) catalysts, f) blowing agents, g) reinforcing agents, h) auxiliary agents, in an open or closed moulding tool, optionally under compression. The invention also relates to the use of alkyl- and/or alkenyl succinic acid amides and/or imides (d) as internal mould release agents for the preparation of moulded bodies made of polyisocyanate polyaddition products.

    Abstract: Sheet-like reinforced materials consisting of A. a core layer comprising a sheet-Like textile structure, preferably a glass fiber mat, B. a plastic matrix composed of a nylon which has been polymerized under alkaline conditions and penetrates both the core layer and the surface layer or layers, are produced batchwise by the RIM method or continuously on a double-belt press by impregnating the sheet-line textile structure and the foam sheets with a lactam melt and polymerizing the latter. The reinforced material can be used for the production of finished articles having a satisfactory surface, for example for the automotive or aircraft industry.

    Abstract: HEAT-CURABLE COMPOSITIONS WHICH ARE STORAGE-STABLE AT ROOM TEMPERATURE AND ARE BASED ON COMPOUNDS HAVING REACTIVE-HYDROGEN ATOMS AND POLYISOCYANATES _ of the Invention 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 discreet 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.
