| Abstract: | In this paper, the etherifying agent glycidyl trimethyl ammonium chloride （GTMAC） by trimethylamine and epichlorohydrin under water were synthesised, then cationic polyvinyl alcohol by reaction of polyvinyl alcohol （PVA） and GTMAC was prepared. The affecting factors in the synthesis of PVA such as the molar ratio between GTMAC and PVA, the pH of reaction solution, reaction tempera- ture, reaction time were studied. The yield of cationic PVA was 96.58%, and the cationic substitution degree was w=97.01%. At the same time, the structure of cationic polyvinyl alcohol was characterized by IR. |
