摘要： Fibrous product is externally sized by applying to the material a basic aqueous dispersion of an interpolymer of an ethylenically unsaturated monomer and an ethylenically unsaturated carboxylic acid comonomer. The preferred dispersions which have lower initial viscosities provide dispersion/starch dilute solutions with higher viscosities and improved external sizing effectiveness. Resulting fibrous products are adequately sized and exhibit excellent printability and strength properties.

摘要： The present pertains to an improved method of internally sizing a cellulosic article and an improved internally sized cellulosic article where a water-dispersible, water- and alkali-insoluble internal sizing agent from an interpolymer of an ethylenically unsaturated hydrocarbon monomer and an ethylenically unsaturated carboxylic acid comonomer is applied to fiber stock or pulp slurry some amount of time subsequent to the instance of application of a retention aid. The invention also includes a novel internal sizing composition where the interpolymer is rendered water-dispersible by reaction with an inorganic neutralizing cationic compound. The improved method is particularly well suited for paper making wherein substantially improved sizing performance is obtainable. Internal sizing agents based on inorganic neutralizing cationic compounds such as, for example, potassium hydroxide, provide the surprising advantage of hard water resistance.

摘要： It has been found that monovinylidene aromatic/conjugated diene/ethylenically unsaturated acid copolymer compositions are provided with good combinations of physical properties when a sulfoalkyl monomer is employed in minor amounts in such polymer in place of emulsifying additive(s). In particular, the combinations of wet and dry pick resistance have been shown to be maintained or improved when paper coating formulations are prepared from latex polymer compositions according to this invention. Sulfoalkyl (meth)acrylate salts and 2-acrylamido-2-methylpropane sulfonic acid salts are shown to be suitable sulfoalkyl monomers for this purpose.
