    摘要: The use of esters--liquid at room temperature--of C.sub.6-22 fatty acids with monohydric alcohols and/or of C.sub.6-22 fatty alcohols with monocarboxylic acids as solvents for isocyanates and/or isocyanurates is provided. Because the ester reduces the viscosity of the isocyanates and/or isocyanurates, the mixture will be easy to pump and mix with other components prior to curing. Also provided is a process for reducing the viscosity of isocyanates and isocyanurates comprising adding to said isocyanate or isocyanurate one or more esters selected from the group consisting of C.sub.6-22 fatty acids with monohydric alcohols and C.sub.6-22 fatty alcohols with monocarboxylic acids, said esters being a liquid at room temperature.

    摘要: A process for producing a polyurethane resin having an extended gel time by reacting a polyol component with a polyisocyanate in an NCO:OH ratio of from 10:1 to 1:10 wherein the polyol component contains from 0.1% to 100% by weight of a randomized castor oil prepared by heating castor oil for between about 0.1 and 15 hours at a temperature of between about 100.degree. C. and 280.degree. C. in the presence of a basic lithium salt.

    摘要: A process is provided for the production of polyaddition and polycondensation products, in which addition products of, on average, 0.5 to 2 moles of ethylene and/or propylene oxide with glycerol are polymerized with polyfunctional isocyanates or polybasic carboxylic acids or carboxylic acid esters a) directly or b) via the intermediate stage of transesterification products with esters of C.sub.1-4 alcohols and C.sub.2-22 fatty acids not including the esters of ricinoleic acid. The addition products of glycerol and ethylene or propylene oxide have been found to be a suitable replacement for trimethylolpropane in such reactions.
