    摘要： The invention relates to two-component polyurethane adhesive preparations in which the resin component is an oleochemical polyol. The oleochemical polyols used are ring-opened products of the reaction of epoxidized fatty alcohols, fatty acid esters (particularly triglycerides) or fatty acid amides with alcohols. The oleochemical polyols may be varied within wide limits in regard to their OH-functionality and so formulated with the hardener polyisocyanate components that the adhesives satisfy the relevant requirements. Reaction products of epoxidized triglycerides with monohydric alcohols are a particularly effective substitute for castor oil.

    摘要： 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.

    摘要： Polyurethane prepolymers containing terminal isocyanate groups in which oleochemical polyols are present as the polyol component. The oleochemical polyols are ring opened products or partial ring-opened products of epoxidized fatty acid triglycerides with alcohols. The use of oleochemical polyols having a residual epoxide number of from 1.0 to 4.0% by weight of epoxide oxygen is preferred. The polyurethane prepolymers are particularly suitable for use in one-component or two-component polyurethane foam formulations.

    摘要： 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).
