WATER POLYMER DISPERSIONS Russian patent published in 2014 - IPC C08L23/02 C08L51/00 C08F2/00 C04B2/00 C04B24/24 

FIELD: chemistry.

SUBSTANCE: invention relates to a water polymer dispersion for the application as an additive for compositions, which contain a hydraulic binding substance or a binding substance with latent hydraulic properties, a multi-component composition for obtaining binding solutions, mortars or cement, a hardened composition for the application in civil engineering construction or building construction, to the said building constructions, as well as to the application of the said water polymer dispersion. The water polymer dispersion contains a) dispersed copolymer, consisting of at least two monomers, selected from the group, consisting of ethylene, propylene, butylenes, isoprene, butadiene, styrene, acrylnitrile, acrylic acid, metacrylic acid, alkylacrylate, alkylmetacrylate, vinyl ether and vinyl chloride, b) comb-like polymer, which has side chains, bound with the main chain by means of ether or ester groups and c) water.

EFFECT: obtaining the water polymer dispersion for the addition in hydraulic and possessing latent hydraulic properties binding substances, which makes it possible to achieve an increase of mechanical properties of the said substances and reduce porosity and water absorption by the said substances.
