Copolymers which are obtainable by reacting acrylic monomers with monomersnof the following formula:n R 4 - O - R 5 - CO - NH - R 6 n wherein R 4 represents H or a group of the following formulae:n R 5 represents an oxyalkenyl group of the following formulae:n - (CHR 1 - CH 2 - O) m - or -(CHR 1 - CH 2 - O) m1 -(CH 2 -CH 2 -O) n - R 6 represents a C 1 -to C 8 -alkyl group, a C 5 - to C 7 -cycloalkyl group, or a phenylngroup. The copolymers are very useful as additives or admixtures for improvingnthe properties of construction materials and of dispersions. |
