文摘内容 This paper deals with the preparation of cationicstarch with high degree of substitute by dry-process.The corn starch and the alkali catalyst are mixed inthe mixer, then added the cationic etherifying agent(3-chloro-2-hydroxypropyltrimethylammoniumchloride). The reacting time is for 5 hours at thetemperature of 70~C. The cationic starch with highdegree of substitution is used as anionic chargeneutralizing agents to improve filler retention inwet-end section ofpapermaking machine。
