    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: Method for activating surfaces of a polymer (A) that contains at least one internal mold release agent (I) by irradiating with ultra-violet (UV) light from a spontaneously emitting source. Independent claims are also included for: (a) method for preparing a composite component (CC) from (A) and a reactive plastic (B); (b) equipment for preparing CC; (c) (A) that contains (I) and has a surface activated by the new method; and (d) CC prepared by method (a).

    Abstract: A laminated element comprises a thermoplastic polymer bonded to the reaction product of a mixture of an isocyanate, a polyester polyalcohol (functionality of 2-3 and a hydroxyl number of 40-400 mgKOH/g), prepared from adipic acid and/or phthalic acid anhydride with polytetrahydrofuran, 1,6-hexanediol, 1,4-butanediol, monoethylene glycol, diethyleneglycol, trimethylolpropane and/or neopentylglycol. A laminated element (I) comprises: (A) a thermoplastic polymer, to which is bonded; (B) the reaction product a mixture comprising (B1) isocyanate (B2) a polyester polyalcohol, having a functionality of 2-3 and a hydroxyl number of 40-400 mgKOH/g, prepared from the condensation of adipic acid and/or phthalic acid anhydride with polytetrahydrofuran, 1,6-hexanediol, 1,4-butanediol, monoethylene glycol, diethyleneglycol, trimethylolpropane and/or neopentylglycol and optionally (B3) catalyst; (C) propellant; and/or (D) additives and processing aids. Independent claims are included for: (i) a process for the production of (I) by the application of (B) onto (A); and (ii) aircraft components, automobile components or furniture containing (I).

    Abstract: Fiber reinforced polyisocyanate polymer product, is prepared in a two step process with and without a blowing agent on either face of the fabric. Fiber reinforced polyisocyanate polymer product is prepared by reaction of: (A) isocyanates, with (B) isocyanate reactive compounds, optionally in the presence of (C) catalysts, (D) blowing agents, and (E) processing aids and/or additive, on (F) a fibrous surface. The surface of (F) is not thoroughly impregnated in a first step by the starting materials (A) and (B), optionally in the presence of (C), (D) and/or (E) or by the product and in a second step reaction between (A) and (B), optionally in the presence of (C) and/or (E) is carried out on the other surface of (F).
