  • Patent number: 6664415
    Abstract: The present invention relates to a process for preparing a low boiling monoisocyanate having a boiling point of between 70 and 320° C. at standard pressure by reacting A) a high boiling isocyanate compound having a boiling point of at least 180° C. at standard pressure and an HC content of at least 50 ppm with B) a monoamine having a primary amino group, at a maximum reaction temperature of 180° C. and a molar ratio of isocyanate groups to amino groups of at least 4:1 to form a compound containing a biuret/urea group, simultaneously thermally decomposing this compound in situ to form a monoisocyanate corresponding to monoamine B) and removing the monoisocyanate by distillation, optionally under vacuum.

  • Patent number: 6521707
    Abstract: The invention relates to novel isocyanates containing tertiary amino groups, a process for preparing them, and also their use for the synthesis and modification of polymers. The invention provides isocyanates of the formula (I) where R1 and R2 are, independently of one another, alkyl having from 1 to 6 carbon atoms, where R1 and R2 may be joined to form a ring, Z is alkylene having from 2 to 6 carbon atoms, n is an integer from 0 to 20, Y is alkylene having from 2 to 6 carbon atoms. The alkyl radicals R1 and R2 may be linear or branched or joined to form an aliphatic ring. The alkylene radical Z preferably contains from 2 to 4 carbon atoms.
