Cp copolymers in the form of a polymer constructed of at least three different monoethylenically unsaturated m monomers

摘要

Cp copolymers in the form of a polymer constructed of at least three different monoethylenically unsaturated m monomers. The invention relates to novel cp cyclopentenes which are incorporated in the form of polymers consisting of at least three different types of monoethylenically unsaturated m monomers and comprising, in the incorporated polymerization form, a) at least one type of monoethylenically unsaturated ml monomer which comprises at least one sulfonic acid group, ß1) at least one monoethylenically unsaturated neutral m2 monomer type whose solubility in water at a temperature of 20 ° C is less than 30 g / l and ß2) at least one monoethylenically neutral m2b monomer type unsaturated water whose solubility in water at a temperature of 20 ° C is greater than 50 g / l.
