摘要:
Disclosed herein is a process for the production of aminophenoxy-terminated polyethers containing recurring structural units corresponding to the following formula--CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --O--comprising reacting:a) a polyether component consisting essentially of a polyether diol containing the afore-stated recurring structural units, withb) a nitrobenzene containing hydroxyl-reactive substituent.
