摘要： In the non-acidic sizing of paper reaction between alkylketene dimer sizing agent and cellulose of cellulosic paper-making fibers is catalyzed by dissolving carbon dioxide in an aqueous vehicle of an aqueous pulp of the paper-making fibers; the carbon dioxide provides bicarbonate ions which catalyse the reaction; the bicarbonate ions may be generated by dissociation of the carbon dioxide in water, or by reaction of the carbon dioxide with calcium carbonate incorporated in the pulp as a filler for the paper, or with some other alkali present.

摘要： Long-chain ketene dimers are prepared in a process in which in the absence of an organic solvent, carboxylic acid chloride is fed, with intensive mixing, into a recipient of triethyl amine at a rate of not more than 3 moles/hour per mole of present triethyl amine, and the mixing rate, feed rate, and heat exchange are so attuned to each other that the viscosity of the mixture always is less than 250 mPa.s, measured at 60.degree. C. (rate of shear higher than 100 l/sec). The process is characterized in that the molar ratio of the total amount of carboxylic acid chloride fed in to the recipient amount of amine is 1:1.025 to 1:2, and, after the conversion, the reaction mixture containing the ketene dimer is treated with diluted aqueous hydrochloric acid or an aqueous solution of triethyl amine hydrochloride and hydrochloric acid, and the ketene dimer is separated. The ketenes prepared in accordance with the present invention are highly suitable for use in paper sizing.

摘要： The present invention relates to a novel sizing composition in the form of an aqueous emulsion comprising a hydrophobic cellulose reactive sizing agent and a cationic polymer comprising a starch, the novel features of said composition being that the starch possesses a combination of (A) a branched, high molecular weight structure as reflected by an amylopectin content of at least 85% and (B) a degree of substitution of about 0.045 to 0.40.Such sizing compositions can be prepared by dissolving the aforementioned starch in water, adjusting the temperature to above the melting point of the sizing agent and adding the sizing agent to the solution so as to form a coarse emulsion, which is subsequently subjected to shear forces to reduce the particle size of the emulsion.The invention also relates to a method of preparing sized paper or paperboard by using the abovementioned sizing composition. Also, the invention relates to the sized paper for paperboard prepared by said method. Such paper products show reduction in liquid absorbency as compared to products using conventional sizing agents, reduced comsumption of optical highteners, and enhanced development of sizing.
