We have developed methodology to synthesise aqueous soluble polymers such as poly(acrylic acid) in flow, enabling access to a variety of molecular weights [L. Brocken, P. D. Price, J. Whittaker and I. R. Baxendale, React. Chem. Eng., 2017, in press]. However, full conversion was hard to achieve without increasing the dispersity and therefore purification was necessary. In this work we demonstrate that flow polymerisation can be directly coupled with purification to furnish a purified polymer sample in under one hour.

使用膜超滤装置在流动中纯化聚丙烯酸

我们已经开发出可以合成流动形式的水溶性聚合物（例如聚（丙烯酸））的方法，从而能够获得各种分子量[L. Brocken，PD Price，J。Whittaker和IR Baxendale，React。化学。，2017年，印刷中]。但是，不增加分散度就难以实现完全转化，因此必须进行纯化。在这项工作中，我们证明了流聚合可以与纯化直接结合，以在一小时内提供纯化的聚合物样品。
