    摘要： The instant invention is directed to a thermoplastic synthetic material, comprising:(A) 75 to 97% by weight of a thermoplastic polyurethane and(B) 25 to 3% by weight of a polymer of olefinically unsaturated monomers, wherein component (B) is a graft product of(a) 5 to 35% by weight, based on the graft product, of one or more graft monomers on(b) 65 to 95% by weight, based on the graft product, of an elastomer component serving as graft base which has a second order transition temperature of below -30.degree. C.,the entire component (B) containing less than 50% by weight of the monomers styrene, .alpha.-methyl styrene and acrylonitrile. The instant invention is also directed to a process for the production of the thermoplastic synthetic materials.

    摘要： The instant invention is directed to a process for the production of fiber-reinforced molded products, comprising:(1) mixing at a temperature of from 10.degree. to 50.degree. 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.
