用传统的加热搅拌法和微波辐射法溶解聚乙烯醇（PVA）后，测定聚乙烯醇黏均相对分子质量，并进行比较。结果表明，用2种方法测得的黏均相对分子质量基本相同，但采用微波辐射法有能使实验时间缩短、实验过程简便的优点。

In this study, viscosity-average molecular weight of polyvinyl alcohol which was dissolved using the traditional heat stirring method and microwave radiation was determined and compared. The results were obtained ： viscosity-average molecular weights of polyvinyl alcohol dissolved by these two methods were the same. However, microwave radiation method had the advantages of short experimental time and simple experiment process.
