Paper sizing using an agent containing uniformly bound octenyl succinic anhydride groups made by the reaction of octenyl succinic anhydride onto a dispersed waxy starch

摘要

The application relates to an agent containing bound octenyl succinic anhydride groups made via the reaction of octenyl succinic anhydride onto a dispersed waxy starch, which provides significant improvements in paper porosity reduction, when added at a low level to a commodity surface starch dispersion and used to surface size paper.
