ABSTRACT:
The invention relates to reaction products of polyetheramines with polymers containing dicarboxylic anhydride groups, which contain 20-80, preferably 40-60, mol % of bivalent structural units A and/or C and, if required, B ##STR1## in which R.sup.1 and R.sup.2, independently of one another, are hydrogen or methyl,
a and b are equal to zero or one and a+b is equal to one,
Y is X or NRR.sup.3,
X is --OH, --O--C.sub.1-30 -alkyl, NR.sup.3 R.sup.4 or --O.sup..crclbar. N.sup..sym. R.sup.3 R.sup.4,
R.sup.3 and R.sup.4, independently of one another, are hydrogen, C.sub.6 -C.sub.40 -alkyl or R,
R is ##STR2## with the proviso that at least 1 mol % of the anhydride groups bonded to the polymer have reacted with a polyetheramine,
Z is C.sub.2 -C.sub.4 -alkyl,
n is a number from 1 to 1000,
R.sup.5 is hydrogen, C.sub.1 -C.sub.30 -alkyl, C.sub.5 -C.sub.12 -cycloalkyl or C.sub.6 -C.sub.30 -aryl and
R.sup.6 is hydrogen or C.sub.1 -C.sub.4 -alkyl, preferably methyl, and
80-20 mol %, preferably 60-40 mol % of bivalent structural units D ##STR3## in which R.sup.7 is hydrogen or C.sub.1 -C.sub.4 -alkyl and
R.sup.8 is C.sub.1 -C.sub.60 -alkyl or C.sub.6 -C.sub.18 -aryl.
