polyether,nobtained by base-catalyzed addition of alkylene oxidesnto toluenediamine, optionally with the use of coinitiators,ncharacterized in that thenTolylenediamine has a content of 2,3- and 3,4-toluenediamine of ≥ 50% by weight,nbased on the total toluenediamine, and the proportionnof ethylene oxide on the total amount of alkylene oxide is 5 to 12% by weight. |
