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: The invention relates to s-triazine radical-containing polyether polyol mixtures having functionalities of from 2 to 6 and hydroxyl numbers of from 210 to 640, prepared by the oxyalkylation of a mixture of one or more polyamino-1,3,5-triazines, preferably melamine, and an alkanol having a hydroxyl functionality of from 2 to 6 and having 2 to 18 carbon atoms, water, or their mixtures, in the absence of catalysts and conventional inert polar solvents. The resulting polyether polyol mixtures are suitable for the preparation of rigid polyurethane, polyisocyanurate, and urethane group-containing polyisocyanuate foams produced by means of the polyisocyanate polyaddition process.

Abstract: The invention relates to urea group-containing polyisocyanate mixtures which are liquid at room temperature and have an isocyanate group content of from 15 to 30 weight percent and a diphenylmethane diisocyanate content of from 55 to 90 weight percent, obtained through the reaction of (A) polyoxyalkylene polyamines having a functionality of from 2 to 5 and an amine number from 20 to 250 with a polyisocyanate (B) selected from the group consisting of (B1) a mixture of diphenylmethane diisocyanates and polyphenyl polymethylene polyisocyanates having a diphenylmethane diisocyanate content of from 55 to 90 weight percent or (B2) at least one diphenylmethane diisocyanate isomer. The polyisocyanate mixtures claimed in the invention are used to prepare dense or cellular polyurethane and/or polyisocyanurate plastics, in particular, flexible polyurethane foams.

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.

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.
