| Abstract: | The cationic starch of high substitution was perpared by modified natural drying process (pre drying dryness process)with cornstarch and 3 chloro 2 hydroxypropyl trimethyl ammonium chloride(CHPTMA).The effect on substitution and reaction efficiency was studied and reaction formula and technics conditions were defined.Performances of product were measured.The results showed that this starch has good dispersion and dissolution and has industrial application value. |
