    摘要： This invention relates to a process for the production of optionally foamed polyurethane plastics, particularly shaped articles, using certain denatured biomasses as reactive fillers. The fillers in question comprise biomasses based on microorganisms and the derivatives and decomposition products of microorganisms, particularly biologically purified sludges, which have been deodorized and irreversibly denatured by reaction with isocyanates and/or carbonyl compounds and compounds capable of aminoplast and/or phenoplast formation.

    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.
