    • The invention relates to optionally solventless two-component polyurethane surfacers containing finely divided fillers in a high pigment volume concentration based on a polyfunctional isocyanate component (B) and a polyol component (A) which is liquid at room temperature and which consists of mixture components containing isocyanate-reactive hydroxyl groups with an at least predominant content of branched-chain polyols (A1) containing ester and ether groups, which contains at least a proportion of the finely divided fillers and, optionally, the additives and which, for application, is mixed with the isocyanate component (B) and applied as a mixture which can still be processed by shaping. To form a substantially waterproof, elastic multipurpose adhesive surfacer which combines high adhesive strength with high volume stability, the polyol component (A) contains oleopolyols having an OH functionality of at least 2 to about 3 as an additional mixture component (A2) and, if desired, low-viscosity monofunctional alcohols of distinctly oleophilic character, which are at least substantially involatile at room temperature, in admixture with component (A1) as another additional mixture component (A3).

    • The invention relates to isocyanate-terminated polyurethane prepolymers containing a stoichiometric excess of an isocyanate component comprised of one or more aromatic isocyanates containing on average from 2 to 4 isocyanate groups per molecule and a polyol component comprised of an oleochemical polyol prepared by epoxidation of a triglyceride containing olefinic unsaturation and subsequent ring opening with an alcohol. In use, accelerators, flameproofing agents, blowing agents and, optionally, liquefying agents, dyes and/or stabilizers, are included. The oleochemical polyol does not contain any free epoxide groups and is obtained by complete ring opening of epoxidized triglycerides of a fatty acid mixture containing at least partly olefinically unsaturated fatty acids with one or more C.sub.1 -C.sub.12 alcohols and partial conversion by alcoholysis or transesterification of the triglyceride derivatives to alkyl ester polyols containing from 1 to 12 carbon atoms in the alkyl radical. A process for the production of these polyurethane prepolymers and to their use as starting materials for the production of polyurethane foams is included.
    • 本发明涉及含有化学计量过量的异氰酸酯组分的异氰酸酯封端的聚氨酯预聚物,所述异氰酸酯组分由每分子平均含有2至4个异氰酸酯基团的一种或多种芳族异氰酸酯组成,多元醇组分由通过甘油三酯环氧化制备的油脂化学多元醇 含有烯属不饱和度,随后用醇开环。 在使用中,包括促进剂,防火剂,发泡剂和任选的液化剂,染料和/或稳定剂。 油化学多元醇不含有任何游离的环氧基,并且是通过将至少部分烯属不饱和脂肪酸与一种或多种C 1 -C 12醇完全开环的脂肪酸混合物的环氧化甘油三酸酯完全开环而得到的,并且通过醇解或酯交换部分转化得到 甘油三酯衍生物在烷基中含有1至12个碳原子的烷基酯多元醇。 包括生产这些聚氨酯预聚物的方法及其用作生产聚氨酯泡沫的原料的用途。
