在本研究中，在实验室规模的管式反应器中进行丙烯酸酯的连续自由基溶液聚合过程的开发。如果在反应器的进料点处存在不良的混合条件，则总是观察到反应器中的结垢。为了增加单体和引发剂的均化，在反应器入口处安装微混合器。微型混合器确保了预热单体和引发剂溶液在微型尺度上的非常快速的混合，并且极大地减少了结垢。所采用的反应器的理论生产能力为每年50公吨。第一个预基础设计已经表明，通过增加数量而不是传统的按比例增加，可以实现每年几千吨的生产能力。
In this study the development of a continuous radical solution polymerization process for acrylates in a lab scale tube reactor was performed. Fouling in the reactor was always observed if there were bad mixing conditions at the feed point of the reactor. In order to increase the homogenization of monomer and initiator a micro mixer was installed at the reactor inlet. The micro mixer ensured a very fast mixing at the micro scale of the preheated monomer and initiator solutions, and fouling was reduced tremendously.The reactor employed has a theoretical production capacity of 50 metric tons per year. A first prebasic design has shown that a production capacity of some thousand tons per year can be achieved by numbering up instead of conventional scale up.
