    摘要： The compounds of the present invention are obtained by the reaction of carbamoyl lactams (from lactams and polyisocyanates) with polyhydric alcohols or monoamino alcohols in the presence of catalytic quantities of a strong basic catalyst, e.g. an alkali metal alcoholate, at elevated temperatures.The polyols contain urea groups and either ester or amide groups and correspond to formula (I) or (II) ##STR1## The polyols are crystalline, relatively high melting compounds which are used as reactants for the synthesis of polyurethane elastomers, in particular in the form of finely divided components in one-component polyurethane reaction mixtures.

    摘要： Low molecular weight 4,4'-diphenylmethane-uretdione-diisocyanates corresponding to the formula: ##STR1## wherein n is a number from 0 to 1,are made by dimerizing diphenylmethane-4,4'-diisocyanate at a temperature of 50.degree. C. or less in a mixture of non-polar and moderately polar solvents in the presence of a dimerization catalyst. The dimerization product may then be worked up at low temperatures (i.e., .ltoreq.50.degree. C.). The dimerization products of diphenylmethane-diisocyanate thus obtained generally have only a small amount of oligomeric uretdione-diisocyanates present. These dimerization products may be used advantageously in the synthesis of polyurethanes.

    摘要： Diisocyanates corresponding to the formula ##STR1## in which R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 (an isocyanate-containing radical) are as defined herein are made by several processes. These diisocyanates may be made by phosgenating the diamine in which the diisocyanate is based. They may also be produced by treating the bis-urethane of the tertiary alcohol corresponding to the diisocyanate with phosgene. Such diisocyanates may also be made by treating a specific type of bis-urea with hydrogen chloride. The diisocyanates corresponding to the above-given formula are particularly useful in the production of polyurethanes having good flame-proof and mechanical properties.

C.,(a) 7 to 35% by weight of a polyisocyanate having a melting point above 100.degree. C., and(b) 14 to 35% by weight of a polyisocyanate which is liquid at the reaction temperature of mixing, with(c) 43 to 62% by weight of one or more compounds having molecular weights of 300 to 10,000 containing 2 to 8 hydroxyl groups, and(d) 3 to 10% by weight of a chain-lengthening agent having a molecular weight of 62 to 250 containing 2 to 4 hydroxyl groups,(e) 0 to 5% by weight of a compound having a molecular weight below 1,000 containing from 2 to 4 amino groups or an equivalent quantity of water,(f) 0 to 5% by weight of a molecular sieve of the sodium aluminum silicate type, and(g) 0 to 5% by weight of one or more activators, all percentages being based on the total weight of (a) through (g) and components (b) through (e) being liquid at the chosen reaction temperature of mixing and having an average functionality of isocyanate-reactive groups of 2.5 to 3.5, the equivalent ratio of isocyanate groups in component (b) to isocyanate-reactive hydrogen atoms in components (c) through (e) being from 0.4:1 to 0.85:1 and the equivalent ratio of isocyanate groups in component (a) to isocyanate-reactive hydrogen atoms in components (c) through (e), taking into account any masked isocyanate groups being from 0.15:1 to 1.2:1, with the proviso that the average functionality of components (c) through (e) should be at least 2.65 when the first-mentioned equivalent ratio is less than or equal to 0.65:1 and not more than 3.0 when the equivalent ratio is greater than or equal to 0.70:1;(2) adding a fiber material having a fiber length of from 10 to 100 mm; and(3) after storing for from one hour to four days, curing and shaping the molding compound at a temperature above 90.degree. C. and at a pressure of from 20 to 300 bars.
