Abstract: High degree of polymerization of PVA was prepared by PVAc with alcoholysis,because of its large molecular weight,to study on alcoholysis process is particularly necessary.This paper discussed the factors affecting the alcoholysis process,such as temperature,reaction time,catalyst concentration,reached a high degree of polymerization of PVAc alcoholysis the optimum.The optimal technological condition of alcoholysis was obtained.
