Abstract: According to the inventive method, the polyurethane foams are produced by reacting isocyanates with compounds that react with isocyanates in the presence of foaming agents and optionally, catalysts, additives and/or auxiliary agents. The method is characterised in that the reaction is carried out in the presence of at least one of the following compounds (i): alpha , beta -unsaturated carboxylic acid, alpha , beta -unsaturated carboxylic acid derivative, alpha , beta -unsaturated ketone and or alpha , beta -unsaturated aldehyde.

Abstract: A process is disclosed for producing self-parting, compact or cellular mouldings made of polyisocyanate polyaddition products, if required containing reinforcing agents, 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 from 62 to 10,000; and optionally (c) chain lengthening and/or cross-linking agents, in the presence of (d) inner parting agents, and in the presence or absence of (e) catalysts; (f) foaming agents; (g) reinforcing agents and (h) additives, in an open or closed moulding tool. The process is characterised in that alkylsuccinic acid esters and/or semi-esters and/or alkenylsuccinic acid esters and/or semi-esters are used as inner parting agents (d).

Abstract: The present invention relates to a process for the preparation of flexible, soft polyurethane foams having viscoelastic, structure-borne sound-proofing properties in a temperature range of from -20.degree.C to +80.degree.C by reacting a) a polyoxyalkylene-polyol mixture containing ai) block polyoxypropylene-polyoxyethylene-polyol mixture having a hydroxyl number of from 14 to 65 and containing from 2 to 9 % by weight of terminal ethylene oxide units, based on the weight of the polyoxypropylene units, prepared by anionic polymerization, at elevated temperatures, of 1,2-propyleneoxide onto an initiator molecule mixture having a mean functionality of from 2.3 to 2.8, comprising water and ylycerol and/or trimethylolpropane, and polymerization of acylene oxide onto the resultant polyoxypropylene adduct, and aii) one or more difunctional and/or trifunctional polyoxypropylene-polyoxyethylene-polyol containing from 60 to 85 % by weight of oxyethylene units, based on the total weight of polymerized alkylene oxide units, and having a hydroxyl number of from 20 to 80, and b) if desired low-molecular-weight chain extenders with c) organic and/or modified organic polyisocyanates in the presence of d) catalysts, e) blowing agents, preferably water, and, if desired, f) auxiliaries and/or additives, and to the polyoxyalkylene-polyol mixtures (a) which can be used for this purpose.

Abstract: Cellular or compact polyurethane-polyurea mouldings are prepd. by reaction of (a) organic polyisocyanates, (b) higher mol. cpds. with at least 2 reactive H, (c) aromatic diamines and opt. (d) other chain extenders and/or cross-linking agents, in presence of (e) internal realease agents, (f) catalysts, and opt. (g) blowing agents and (h) auxiliaries and/or additives, as a one-shot system, in closed moulds, by reaction injection moulding. The internal release agent (e) is (A) 0.1-10 wt.%, w.r.t. (b)-(d), a mixt. of (i) 5-80 pts. wt. of an amine and/or cyclic lactam, (ii) 20-95 pts. of a metal salt of stearic and/or isostearic acid, and (iii) 0-5 pts. of a metal salt of a mon- and/or di-carboxylic acid, and (B) 0.01-2 wt.%, w.r.t. (b)-(d) of a mono- and/or di-carboxylic acid or anhydride. The release agent is claimed.
