Abstract: Water-soluble polymers (I) of esters of acrylic acid (II) and alkyl-polyalkylene glycols (III) are obtained by a method involving azeotropic esterification of (II) and (III) in presence of organic solvent followed by radical polymerisation of the mixture with removal of solvent by azeotropic distillation and replacement of the lost water. Water-soluble polymers (I) of esters of acrylic acid (II) and alkylpolyalkylene glycols (III), obtained by azeotropic esterification of a mixture of (II) and (III) in a mol ratio of (2-3):1 in presence of at least 85 wt% (based on III) of an organic solvent which forms an azeotrope with water, followed by radical polymerisation of the resulting mixture with azeotropic distillation to remove the solvent and with replacement of lost water by recycling or by the addition of fresh water. An Independent claim is also included for a method for the production of (I) as described above.

Abstract: Alkylpolyalkylene glycol esters of monoethylenically unsaturated carboxylic acids are prepared by esterifying (a) monoethylenically unsaturated carboxylic acids with (b) polyalkylene glycols which are endcapped at one end, in the absence of a solvent and in the presence of polymerization inhibitors and esterification catalysts at not more than 160° C. by a process in which the esterification is first carried out under atmospheric pressure or at up to 50 bar, the water formed in the esterification is then distilled from the reaction mixture at from 10 to 500 mbar and the esterification is then continued under atmospheric pressure or at up to 50 bar.
