Patent ID: 8129326

Claim:
A polymer, obtained by a process comprising: a) condensing at least one of an N-(hydroxyalkyl)amine of formula (I.a) and an N-(hydroxyalkyl)amine of formula (I.b), wherein A are independently selected from the group consisting of C 1 -C 6 -alkylene groups; R 1 , R 1 *, R 2 , R 2 *, R 3 , R 3 *, R 4 , R 4 *, R 5 , and R 5 * are independently of one another selected from the group consisting of hydrogen, alkyl, cycloalkyl, and aryl, wherein the alkyl, cycloalkyl, and aryl are optionally substituted, and R 6 is selected from the group consisting of hydrogen, alkyl, cycloalkyl, and aryl, wherein the alkyl, cycloalkyl, and aryl are optionally substituted, in the presence of an acid, to obtain at least one N-(hydroxyalkyl)amine polyether; and b) reacting at least a part of the remaining hydroxy groups of the at least one N-(hydroxyalkyl)amine polyether and, optionally, at least a part of secondary amino groups, of the polyether obtained in the reacting a) with at least one alkylene oxide, to obtain an alkoxylated polyether.
