Abstract

Procedimiento para la obtención de papel, con elevada resistencia en seco y baja resistencia en mojado tratando la superficie del papel con sales hidrosolubles de polimerizados a base de ácidos carboxílicos etilénicamente insaturados, caracterizado porque comprende las etapas de polimerizar de 90 a 30% en peso de ácido acrílico y/o ácido metacrílico; de 10 a 70% en peso de acrilonitrilo, metacrilonitrilo, acrilamida y/o metacrilamida; así como, en caso dado, hasta un 30% en peso de un éster de ácido acrílico o ácido metacrílico; y aplicar sobre la superficie del papel los polimerizados resultantes en forma de sales alcalinas y/o alcalinotérreas hidrosolubles, que en solución acuosa al 2% a una temperatura de 20ºC tienen una viscosidad de 5 a 100 mPas (viscosímetro de Brookfield, 20 revoluciones por minuto), en una cantidad de 1 a 4% en peso, en cada caso referido a los sólidos.Procedure for obtaining paper, with high dry strength and low wet strength, treating the surface of the paper with water-soluble salts of polymers based on ethylenically unsaturated carboxylic acids, characterized in that it comprises the steps of polymerizing from 90 to 30% by weight of acrylic acid and/or methacrylic acid; from 10 to 70% by weight of acrylonitrile, methacrylonitrile, acrylamide and/or methacrylamide; as well as, if appropriate, up to 30% by weight of an acrylic acid ester or methacrylic acid; and applying the resulting polymers to the surface of the paper in the form of water-soluble alkaline and/or alkaline-earth salts, which in 2% aqueous solution at a temperature of 20ºC have a viscosity of 5 to 100 mPas (Brookfield viscometer, 20 revolutions per minute ), in an amount of 1 to 4% by weight, in each case based on the solids.
