A process for preparing an etherified polyoxyalkylene derivative of the formula ##STR1## wherein R 1 and R 4 are identical or different and are each independently C 1 -C 20 alkyl, C 3 -C 5 alkenyl, C 6 -C 20 aryl, C 6 -C 20 alkyl aryl, C 6 -C 20 cycloalkyl, and mixtures thereof, R 2 and R 3 are identical or different and independent of each other are H, CH 3 , CH 3 CH 2 , and mixtures thereof, m, m' and n are identical or different and are each greater than or equal to zero, with the proviso that m+m'+n is from 3 to 300; by reacting a polyoxyalkylene compound of the formula. |
