A process for preparing an etherified polyoxyalkylene derivative of the formula (See Fig. I) wherein R1 and R4 are identical or different and are each independently C1-C20 alkyl, C3-C5 alkenyl, C6-C20 aryl, C6-C20 alkyl aryl, C6-C20 cycloalkyl, and mixtures thereof, R2 and R3 are identical or different and independent of each other are H, CH3, CH3CH2, 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 -18-
Un procédé pour préparer un dérivé éthérifié de polyoxyalkylène de formule (Voir Fig. I) où R1 et R4 sont identiques ou différents et sont, indépendamment l'un de l'autre, un alkyle en C1-C20, un alkényle en C3-C5, un aryle en C6-C20, un alkylaryle en C6-C20, un cycloalkyle en C6-C20, et des mélanges de ces derniers, R2 et R3 sont identiques ou différents et sont, indépendamment l'un de l'autre, un H, CH3, CH3CH2, et des mélanges de ces derniers, m, m' et n sont identiques ou différents et sont tous deux supérieurs ou égaux à zéro, à la condition que la somme m + m' + n soit comprise entre 3 et 300; en faisant réagir un polyoxyalkylène de formule -18-
