Abstract
Polyoxyalkylene polyether amino alcohols are prepared which have the following formula: ##STR1## wherein, R represents hydrogen or a methyl or an ethyl group, x represents a number having an average value of about 1 to about 4 and n represents a number having an average value of about 1 to about 40. The polyoxyalkylene polyether amino alcohol is prepared by alkoxylating a glycol that contains one tertiary hydroyxl group and also a primary or secondary hydroxyl group in order to form an alkoxylated intermediate and by then reductively aminating the alkoxylated intermediate.
