Abstract

A process for the suspension polymerization of vinyl chloride is disclosed, according to which the suspension is withdrawn from the reactor prior to attaining 70% conversion, and is recycled to the reactor via an external tube which is externally cooled. By suitably modifying the internal profile of the tube, the results can be improved. The apparatus including a tube with a suitably modified internal profile constitutes another aspect of the invention.
