一种协议,用于聚合催化剂,链转移聚合,聚乙烯表征和反应动力学分析的高通量分析,提出。

该程序的总体目标是建立高通量聚合,并通过对所得聚合物的详细表征和动力学分析来评估催化剂进行链转移的能力。该方法有助于回答与新设计的催化剂相关的聚合催化中的关键问题,这些催化剂可以利用链转移产生通往各种聚合物的有效途径。该技术的主要优点是高通量聚合可实现高效的催化剂筛选,并在各种反应条件下直接比较催化剂。

演示这项技术的将是我实验室的博士后 Ryan Hugh 博士。首先,将 1 毫升两个三丁烷二元和 2.8 毫升两个六甲基安宁溶解在 20 毫升甲醇中,放入 100 毫升圆底烧瓶中。加入 0.4 毫升甲酸后,在室温下搅拌反应物,直到二胺沉淀,通常为 1 至 2 小时。
