Abstract: PROBLEM TO BE SOLVED: To provide a water-soluble polymer useful as an additive to a cementitious composition and its manufacturing method. SOLUTION: The water-soluble polymer of an ester comprises acrylic acid, methacrylic acid and an alkylpolyalkylene glycol and is obtained by subjecting a mixture of acrylic acid (A), methacrylic acid (B) and the alkylpolyalkylene glycol (C) having a moleclar weight (Mw ) of 350-4,000 to an azeotropic esterification in the presence of at least 85 mass%, based on the alkylpolyalkylene glycol (C), of an organic solvent forming an azeotropic mixture with water, subsequently free-radically polymeizing in an aqueous medium a mixture obtained during the esterification while removing the organic solvent during the polymerization by azeotropic distillation from the reaction mixture, and returning water removed by distillation to the mixture or feeding fresh water for replacement.

Abstract: PROBLEM TO BE SOLVED: To provide a water-soluble polymer useful as an additive to cementitious compositions. SOLUTION: The water-soluble polymer is a water-soluble polymer of an ester made from acrylic acid and an alkylpolyalkylene glycol which can be obtained by azeotropic esterification of a mixture of acrylic acid and the alkylpolyalkylene glycol (in a molar ratio of 2 to 3:1) in the presence of at least 85 mass%, based on the alkylpolyalkylene glycol, of an organic solvent which forms an azeotrope with water, followed by free-radical polymerization, in an aqueous medium, of the mixture obtained during the esterification while azeotropically distilling off the organic solvent from the reaction mixture during this polymerization and returning the water removed by distillation to the reaction mixture or replacing the water by a feed of fresh water.

Abstract: The invention relates to a method for producing water soluble polymers of esters from ethylenically unsaturated carboxylic acids and polyalkylene glycols by azeotropic esterification of ethylenically unsaturated carboxylic acids with polyalkylenglycols which are closed at one side by end groups. Esterification is performed in the presence of organic solvents which together with water form an azeotrope of at least 85 weight %. Subsequent radical polymerization is performed on the esters thus obtained thereby optionally together with other ethylenically unsaturated monomers in an aqueous medium. The organic solvent is azeotropically strip distilled out of the reaction mixture during the polymerization process and strip distilled water is reintroduced or the amount of water strip distilled out of the reaction mixture is replaced by adding fresh water.

A water soluble polymer (I) comprising esters of acrylic acid, methacrylic acid and alkylpolyalkyene glycols, is prepared by esterification of a mixture of acrylic acid (A), methacrylic acid (B) and an alkylpolyalkylene glycol (C) having a mol.wt. (Mw) of 350-4000 in a molar ratio of (A) to (C) of 0.1-4:1, a molar ratio of (B to (C) of 1-5:1 and molar ratio of the sum of (A) and (B) to (C) of 2-6:1, in the presence of an organic solvent that forms an azeotrope with water to at least 85 wt.% (w.r.t. (C)), followed by radical polymerization of the resulting mixture in an aqueous medium, whereby the organic solvent is azeotropically distilled off from the reaction mixture during the polymerization and the distilled water is recycled to the mixture or is replaced by the addition of fresh water.
