    Abstract: PROBLEM TO BE SOLVED: To improve the surface strength, printability, and water resistance of paper or a material by the application of paper sizing using a sizing agent containing a converted starch.SOLUTION: A converted starch is made by the reaction of octenyl succinic anhydride onto a waxy starch through the following steps a) to f), wherein an agent provides significant improvements in paper porosity reduction, when added at a low level to a commodity type surface starch dispersion and used to carry out surface sizing. A process comprises: a) slurrying a waxy starch and gelatinizing the slurry; b) optionally cooling the dispersion; c) optionally acidifying the optionally cooled slurry and waiting until the optionally acidified slurry reaches a funnel viscosity of from about 20 seconds to about 30 seconds; d) reacting the dispersion from the step c) with octenylsuccinic anhydride; e) mixing the reacted slurry with the converted starch; and f) applying the starch dispersion to paper.
