  • Publication number: 20090301891
    Abstract: The invention relates to a device for the electrolytic coating of a structured or full-surface base layer (9) on a surface of a substrate (7), which comprises at least one electrolyte bath (3) having at least one rotatably mounted roller (2) connectable as a cathode, which contacts the base layer (9) during the electrolytic coating, the base layer (9) being covered by an electrolyte solution (5) contained in the electrolyte bath (3) and being moved relative to the at least one roller (2) during the coating. The at least one roller (2) connectable as a cathode is connected cathodically during the contact with the base layer (9) and is connected neutrally or anodically as soon as there is no contact with the base layer (9).

  • Patent number: 6872848
    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.
