COPOLYMER AND HYDRAULIC BINDER COMPOSITION

COPOLYMER AND HYDRAULIC BINDER COMPOSITION

A copolymer may be obtained by polymerization reaction(s) using an anionic monomer and two polyethoxylated monomers. Such copolymers may have a polydispersity index, determined by size exclusion chromatography (SEC), of less than 3, and be obtained by at least one radical polymerisation reaction in...

Zusammenfassung:A copolymer may be obtained by polymerization reaction(s) using an anionic monomer and two polyethoxylated monomers. Such copolymers may have a polydispersity index, determined by size exclusion chromatography (SEC), of less than 3, and be obtained by at least one radical polymerisation reaction in water at a temperature ranging from 10 to 90° C. A composition may include such copolymers. Such copolymers may be prepared and use as a superplasticizer for a hydraulic binder composition.
