| 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) n where n R 1 and R 2 are, independently of one another, alkyl having from 1 to 6 carbon atoms, where R 1 and R 2 may be joined to form a ring, n Z is alkylene having from 2 to 6 carbon atoms, n n is an integer from 0 to 20, n Y is alkylene having from 2 to 6 carbon atoms. n The alkyl radicals R 1 and R 2 may be linear or branched or joined to form an aliphatic ring. The alkylene radical Z preferably contains from 2 to 4 carbon atoms. |
