| Abstract: | Polyvinyl alcohol(PVA)of etherification modification was synthesized by reaction of PVA and epichlorohydrin(EPIC),with 10% NaOH as catalyst and EPIC as etherifying agent,as well as the structure of etherification modification product was characterized by FT-IR.The influence on degree of etherification for PVA's modification by technologcial conditions was investigated.The experiment results showed that the reaction temper- ature was 65℃,the reaction time was 6 h,the molar ratio of PVA and EPIC was 1.0:1.5,the degree of etherifica- tion arrived 49.1%. |

| Keywords: | polyvinyl alcohol epichlorohydrin modification degree of etherification |
