Abstract
Provided are cationic comb polymers, obtainable by polymerizing a monomer mixture, which contains at least one monomer having at least one cationic group covalently bonded to the monomer and which contains at least one monomer of the formula R1—O-[AO]n—R2, wherein R1 is an alkenyl group, R2 represents H, an alkyl group having 1 to 20 C atoms, or an aryl group or alkylaryl group having 7 to 20 C atoms, A independently of one another represents a C2 to C6 alkylene group, and n is a value from 2 to 300. Also provided are hydraulically setting cement compositions, shaped bodies, uses, and methods for producing comb polymers. Also provided are novel comb polymers with cationic side chains and structural subunits that comprise polyether components. Further provided are hydraulically setting cement compositions, shaped bodies, uses and methods for producing comb polymers.
