| 摘要 |
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)whereR1 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.
