Polymer dispersity index pdi 是聚合物分散性指数

WebDispersity is firmly established as the standard measure of dispersion in molecular weight distributions. However, it can be misleading, particularly when applied to the relatively narrow molecular weight distributions obtained via living or reversible deactivation polymerizations. The use of the standard deviation is recommended as an alternative. http://www.cjcu.jlu.edu.cn/CN/10.7503/cjcu20240865
