    摘要: A process for the preparation of homogeneous and cellular polyurethane plastics by the reaction of(a) organic polyisocyanates;(b) compounds containing at least 2 Zerewitinoff-active hydrogen atoms and having molecular weights of from 400 to 10,000;(c) chain extenders, and, optionally, additional(d) short-chained compounds containing at least 2 Zerewitinoff-active hydrogen atoms and having a molar mass of from 32 to 400, as well as, optionally,(e) catalysts, blowing agents and other known additives,is described, which is characterized in that 1,4-3,6-dianhydro-hexites, preferably 1,4-3,6-dianhydro-D-sorbitol and/or 1,4-3,6-dianhydro-D-mannitol, optionally mixed with lower molecular weight compounds, preferably with polyols having a molecular weight of from 62 to 400, particularly preferably butane diol-1,4 are used as the chain extenders. The new chain extenders produce high quality elastomers and foams.

    摘要: The present invention relates to substantially colorless organic polyisocyanates, optionally in solution in an inert solvent, having a Hazen color index according to DIN 53 409 of at most 60 and a yellow value according to DIN 6167 of at most 3.0, characterized by a content of about 0.01 to 1 ppm (by weight), based on polyisocyanate, of an organic dye soluble in the polyisocyanate and having an absorption maximum of about 560 to 590 nm or a mixture of such dyes.The present invention also relates to two processes for preparing the substantially colorless organic polyisocyanates. In the first process, the organic dye is added to the prepared polyisocyanate while in the second process the organic dye is added to the starting materials used to prepare the polyisocyanate. Finally, the present invention is directed to the production of polyisocyanate polyaddition products from the substantially colorless organic polyisocyanates and isocyanate-reactive compounds.
