    Abstract: PROBLEM TO BE SOLVED: To simplify a production method for a material usable as a radical crosslinking agent for a high-absorbent material.SOLUTION: A method for producing a crosslinked hydrogel is provided, in which a polyalcohol A is reacted with an ethylenically unsaturated carboxylic acid B in the presence of an esterification catalyst C, a polymerization inhibitor D, and optionally a solvent E which forms an azeotrope with water under the formation of an ester F. Optionally, at least a part of water produced is removed from a reaction mixture, optionally the reaction mixture is neutralized, and the solvent E is removed by distillation, and/or stripped using a gas which is inert under reaction conditions. The reaction mixture from one of the steps, optionally an additional monoethylenically unsaturated compound N, and optionally a copolymerizable hydrophilic monomer M are polymerized in the presence of a radical initiator K and optionally a graft base L. Optionally, the reaction mixture obtained is subjected to post crosslinking, drying, pulverization, and/or screening.

    Abstract: Disclosed is a method for producing (meth)acrylates of C10 alcohol mixtures by reacting (meth)acrylic acid with an isomer mixture of C10 alcohols comprising 2-propylheptanol as the main isomer and at least one of the C10 alcohols 2-propyl-4- methylhexanol, 2-propyl-5-methylhexanol, 2-isopropylheptanol, 2-isopropyl-4- methylhexanol, 2-isopropyl-5-methylhexanol, and/or 2-propyl-4,4-dimethylpentanol in the presence of at least one acid catalyst and at least one polymerization inhibitor and in the presence of a solvent forming an azeotrope along with water, removing the azeotrope by distillation and condensing the same such that the condensate is decomposed into an aqueous and an organic phase. According to said method, a) the esterification process is carried out in a reactor comprising a circulating evaporator, b) in the presence of a solvent, and c) the raw product is purified in a subsequent pure distillation process.
