| 摘 要： | 利用凝胶渗透色谱柱G4000HXL、G3000HXL(两柱串联),紫外检测系统测定高粘度切片的分子质量分布速度快,重复性好,实验数据点均落在直线上,线性良好,满足直线方程lgM=a+btR。与常规切片比较,高黏度切片分散系数小。可以依据分子质量分布来合理地选择原料和加工条件。

| Abstract: | The GPC columns G4000H_(XL),G3000H_(XL)(two columns series connection)and the ultraviolet determination system were used to determine the molecular mass distribution of high viscosity PET chip.In this way,the determination speed is fast,the repeatability is good,the experiment data are all stay on the rectilinear,the linearity is fine,The rectilinear equation lg M = a bt _R is meeted.Compared with normal PET chip,the dispersion coefficent is minor.The material and processing condition can be reasonable selected according to the molecular mass distribution. |
