摘　　要：论文采取了微波辐射法溶解聚乙烯醇,测定其粘均相对分子量,克服了原溶解方法的不足。通过改变微波辐射功率、反应时间、反应温度、溶液浓度找到了最佳辐射条件,并与传统的水浸泡加热法进行了对比。This paper takes microwave radiation to dissolve polyvinyl alcohol and to mensurate the viscosity-average molecular weight of polyvinyl alcohol. The microwave radiation overcomes the shortcomings of the original dissolution method. The optimum radiation condition is found by changing the microwave radiation power,reaction time,reaction temperature,and concentration. And microwave radiation is compared with conventional water heating method during experiment process.
