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: La invencion se refiere a un proceso para la preparacion de cuerpos moldeados compactos o celulares, de autoliberacion que contienen opcionalmente agentes de refuerzo y elaborados a partir de productos de poliadicion de poliisocianato mediante la reaccion de a) poliisocianatos orgánicos y/o orgánicos modificados con b) al menos un compuesto con al menos dos átomos de hidrogeno reactivos y un peso molecular de 500 a 9000 y, opcionalmente c) agentes de extension de cadena y/o de reticulacion en presencia de d) monoamidas de ácido alquil y/o alquenil succínico, monoamidas de ácido alquil y/o alquenil succínico, monoimidas de ácido alquil y/o alquenil succínico, poliamidas, poliimidas, monoamidmonoimidas, poliamidimidas, poliimidas, monoamidmonoimidas, poliamidimidas, amidpoliimidas y poliamidpoliimidas de poli(ácido alquil succínico)- y/o poli(ácido alquenil succínico) o mezclas de las mismas como agentes internos de liberacion de molde, y también en presencia o ausencia de e) catalizadores, f) agentes de expansion, g) agentes de refuerzo, h) agentes auxiliares, en una herramienta de moldeo abierta o cerrada, opcionalmente bajo compresion. La invencion se refiere también al uso de amidas y/o imidas de ácido alquil-y/o alquenil succínico (d) como agentes internos de liberacion de molde para la preparacion de cuerpos moldeados elaborados a partir de productos de poliadicion de poliisocianato.
