    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: The invention relates to a method for electrolytically coating metalswith zinc or a zinc alloy. Matt surfaces are obtained by depositing zinc from an electrolyte solution containing a zinc salt selected from zinc sulphate or an alkane sulphate of zinc or mixtures thereof and optionally other metal salts, an acid selected from sulphuric acid or an alkane sulphonic acid or a mixture of both acids and at least one additive for improving surface roughness and for avoiding dendritic edge growth, selected from surface active compounds containing nitrogen which can be ionic or non-ionic, anionic surface active compounds containing nitrogen, and surface active compounds derived from multi-fuctional alcohols with at least three hydroxy groups. The invention also relates to an electrolytic composition for an electrolytically coating of metals with zinc or zinc alloys, in addition to the use of the above-mentioned additives for improving surface roughness and avoiding dentritic edge growth when metals are electrolytically coated with zinc or a zinc alloy in an electrolyte containing alkane sulphonic acid.

    Abstract: Water soluble polymer comprising esters of acrylic acid, methacrylic acid and alkylpolyalkyene glycols, is prepared by esterification followed by radical polymerization of the resulting mixture in an aqueous medium, whereby the organic solvent is azeotropically distilled off during the polymerization and recycled to the mixture or is replaced by the addition of 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.
