EMULSIFYING POLYMERS AND USE THEREOF Russian patent published in 2012 - IPC C04B40/00 C08F220/06 C08F212/06 C08F212/08 C08F218/00 C08F222/02 C08F222/08 C08F222/40 

FIELD: chemistry.

SUBSTANCE: invention relates to emulsifying polymers and use of these polymers for stable emulsification of hydrophobic additives in aqueous concrete plasticisers. Disclosed is a polymer P, obtained via copolymerisation (a) of at least one ethylenically unsaturated monomer A selected from a group consisting of unsaturated mono- and dicarboxylic acids, sulphonic acids, phosphonic acids in form of free acids or salts or partial salts or halide or anhydride, with (b) at least one ethylenically unsaturated monomer B of formula ,

or ,

where radicals and coefficients are as described in the claim and (c) with at least one ethylenically unsaturated monomer C of formula

,

where radicals and coefficients are as described in the claim and with (d) at least one ethylenically unsaturated monomer D of formula

,

where radicals and coefficients are as described in the claim and optionally (e) with at least one basic ethylenically unsaturated monomer E of formula ,

where radicals and coefficients are as described in the claim and optionally (f) with at least one other ethylenically unsaturated monomer W. Use of the polymer as a plasticiser for water-curable compositions and a water-curable composition are also disclosed.

EFFECT: polymer improves quality of mortar.
