Acrylic copolymers

摘要

Copolymers which are obtainable by reacting acrylic monomers with monomers of the following formula: R4 - O - R5 - CO - NH - R6 wherein R4 represents H or a group of the following formulae: <CHEM> R5 represents an oxyalkenyl group of the following formulae: - (CHR1 - CH2 - O)m- or -(CHR1 - CH2 - O)m1-(CH2-CH2-O)n- R6 represents a C1-to C8-alkyl group, a C5 - to C7 -cycloalkyl group, or a phenyl group. The copolymers are very useful as additives or admixtures for improving the properties of construction materials and of dispersions.
