    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: Low shrinkage nylon moldings are produced by activated alkaline lactam polymerization, preferably using the reactive injection molding technique, by a process wherein the polymerization is carried out in the presence of from 5 to 80% by weight of a polymer P which 1. is completely soluble in the lactam, 2. separates out in the course of polymerization at a conversion of from 1 to 50%, 3. is composed of one or more blocks which are compatible with polylactam and one or more blocks which are incompatible therewith, and preferably 4. possesses functional groups which are incorporated into the growing polylactam chain.
