    摘要: A process is disclosed for the preparation of styrene/acrylic type polymers which are useful in the sizing of paper. The process comprises polymerizing the monomers in an alcohol/water mixture at reflux temperature in the presence of a free-radical generating catalyst. The catalyst is added portion-wise over the course of the reaction and the resultant polymer is neutralized while substantially simulaneously separating the alcohol/water mixture and adding water to recover a product of less than 25% polymer solids.

    摘要: The invention relates to an aqueous sizing composition comprising (a) an emulsion comprising an alkenylsuccinic anhydride component containing alkenylsuccinic anhydride particles suspended in a first starch component containing emulsifying starch selected from the group consisting of non-ionic starches, ionic starches, and mixtures thereof, and (b) a second starch component selected from the group consisting of non-ionic starches, ionic starches and mixtures thereof, such that the alkenylsuccinic anhydride and the starch in the emulsion and the second starch component are present at a starch: alkenylsuccinic anhydride weight ratio that is sufficiently high to enable the sizing composition to impart useful sizing properties to a fibrous substrate when the sizing composition contacts the fibrous substrate. The invention also relates to fibrous substrates treated with the sizing composition, processes for making the composition and processes for using such a composition, and other compositions. In one embodiment, alkylene ketene dimer is used instead of alkenylsuccinic anhydride.

    摘要: This invention relates to paper sizing compositions comprised of at least one sizing agent selected from ASA, AKD and rosin where the at least one sizing agent is emulsified in water, at least one emulsion stabilizer, and from about 0.01% to about 15% by weight of at least one hydrophobic substance, based on the total weight of sizing agent present, provided that the hydrophobic substance is not highly alkoxylated. The sizing promotion efficiency of the paper sizing compositions, as determined by at least one method selected from the Cytec size testing method, the Hercules size testing method, and the Cobb size testing method, is greater than or equal to about 4. Exemplary hydrophobic substances include fatty acid esters, triglycerides, hydrocarbons, esters and/or amides derived from ASA, silicone oils, alcohols, and stearic anhydride. The invention also relates to methods for sizing paper products with these paper sizing compositions and paper or paperboard treated with these sizing compositions.
