高聚物相对分子质量的测定是一重要的研究数据.粘度法设备简单,操作方便且具有很好的实验精度,是常用的方法之一,但若实验条件选择不当,则误差很大.通过实验及查找相关文献,探索并归纳了影响粘度法测高聚物相对分子质量成败的因素,包括客观条件的影响、乌式粘度计的影响、溶液浓度的选择与配制、恒温槽控温精度的影响和其他影响因素。
Abstract:The relative molecular weight of high polymer is a important data in research. The viscosity method is simple, convenient and accurate, it is a common method, but the experimental result is not very satisfactory if the selected condition is ill-suited. Through experiments and docu- mentary research, explores and concludes the reasons of success or failure of the experiment.
