Abstract: The invention relates to a process for the production of flexible, elastic mouldings containing urethane groups having a compacted peripheral zone and a cellular core by reacting a) organic and/or modified organic polyisocyanates with b) at least one relatively high-molecular-weight compound containing at least two reactive hydrogen atoms and optionally c) low-molecular-weight polyhydric alcohols and/or low-molecular-weight polyoxyalkylene-polyols, in the presence of d) an internal mould release agent comprising A) from 0.1 to 12% by weight, based on the total weight of (b) or (b) and (c), of a mixture comprising i) from 60 to 90 parts by weight of at least one organic amine, ii) from 10 to 40 parts by weight of at least one ketimine and iii) from 20 to 95 parts by weight of at least one metal salt of stearic acid, and B) from 0.01 to 32% by weight, based on the total weight of (b) or (b) and (c), of at least one organic mono- and/or dicarboxylic acid or carboxylic anhydride thereof, and e) catalysts, f) blowing agents, and optionally g) auxiliaries and/or additives, in a closed mould with compaction, and to the internal mould release agents which are suitable for this purpose.

Abstract: Reinforced cellular or noncellular molded polyurethane parts are prepared by heating a mixture of reinforcing materials and a heat-curable composition of polyisocyanates and polyols in an open or closed mold, said composition being storage-stable at room temperature and containing, optionally, auxiliaries and additives. In said composition, the polyisocyanate is dispersed in the form of discreet particles having particle diameters from 0.1 to 150 mu m in the polyol and the polyisocyanate particles are deactivated on their surfaces such that from 0.01 to 20 equivalent percent of the total available isocyanate groups are deactivated and such that the ratio of free isocyanate groups to hydroxyl groups is from 0.7:1 to 2.5:1. The polyurethane molded parts are suitable for use as self-supporting trim parts, reinforcement parts, or molded parts for various applications.

Abstract: 1. An adduct obtained by a functionality of 2 to 6, a hydroxyl number of 20 procedure analogous to the Michael reaction, by reacting a) an olefinically unsaturated polyester polyol having to 800, an acid number of 0 to 15 and a molecular weight of 150 to 3000 per double blond, with b) 0.1 to 1 mole, per mole of olefinically unsaturated double bond of component (a), of an alkylene polyamine of the formula H2 N-R-NH-R'-X, where X is an NH2 or OH group, and R and R' are identical or different, linear or branched alkylene radicals of 2 to 12 carbon atoms.

Abstract: Inorganic fillers, in particular glass fibres, for reactive plastic systems are coated on the surface with 0.1 to 16% by weight of a polymer which has a toluene solubility at 100 DEG C of greater than 1% by weight and a caprolactam solubility of less than 0.1% by weight.

Abstract: Low-shrinkage, cellular mouldings based on polycaprolactam having a cell-free outer skin which contain, in the interior, gas-filled cells having a mean diameter of 0.2 mm are obtained by activated anionic polymerisation of an intimate mixture of liquid caprolactam and an inert gas.

Abstract: Crystallite suspensions containing from 3 to 70 weight percent of a crystalline, ethylenically unsaturated polyester prepared through condensation polymerization, and having a molecular weight factor per double bond of 154.4 to 408, as the dispersed phase, and from 30 to 97 weight percent of a polyhydroxyl compound having a functionality of from 2 to about 8, a hydroxyl number of from 20 to 800, and a melting point of less than 30 DEG C. as the coherent phase are suitable for preparing non-cellular and cellular polyurethane- or polyurethane group-containing polyisocyanurate foams.
