(54) Verfahren zur Steuerung der Oberflächeneigenschaften in einer Papiermaschine und Gebrauch des Verfahrens zur Oberflächenbehandlung in einer Papiermaschine


(57) The present invention relates to a method of controlling the surface properties of surfaces in a paper machine by virtue of treating said surfaces with a surface treatment compound to achieve desired surface properties. According to the invention, the surfaces are treated with a liquid surface treatment compound whose characteristics are controlled by modifying the backbone polymer chain of the surface treatment compound advantageously by halogenated macrooligomers, diols, triols, thiols and/or other polyols. The invention also concerns the use of the method in the surface treatment of surfaces in a paper machine.
