Knowledge of molecular weight is an integral factor in polymer synthesis, and while many synthetic strategies have been developed to help control this, determination of the final molecular weight is often only measured at the end of the reaction. Herein, we provide a technique for the online determination of polymer molecular weight using a universal, solvent-independent diffusion ordered spectroscopy (DOSY) calibration and evidence its use in a variety of polymerization reactions.
分子量的知识是聚合物合成中的一个不可或缺的因素，虽然已经开发了许多合成策略来帮助控制分子量，但最终分子量的测定通常只在反应结束时进行。在此，我们提供了一种使用通用的、与溶剂无关的扩散有序光谱（DOSY）校准在线测定聚合物分子量的技术，并证明了其在各种聚合反应中的应用。
