✦ Synopsis

It has been demonstrated earlier that a

Pulsed Packed Column is a suitable reactor for continuous emulsion polymerisation of styrene. The emulsion polymerisation of viny2 acetate follows a different mechanism, which renders the process more liable to instabilities when carried out in a continuous flow reactor. It was demonstrated that emulsion polymerisation of vinyl acetate in a Pulsed Packed Column can be carried out in a stable manner, and with a sufficient reaction rate, provided the rate of backmixing is limited. Introduction. Two mechanisms of emulsion polymerisation have been described in the Iiterature. Mechanism A applies for sparsely water soluble monomers like styrene, mechanism B applies for moderately soluble monomers like vinyZ acetare. In both mechanisms the radical chain reaction starts with the decomposition of an initiator in the water phase. According to

## Abstract The effect of the geometrical and operational parameters on the mixing characteristics of a Couette–Taylor vortex flow reactor (CTVFR) were investigated and were correlated with the same parameters by using the tank‐in‐series model. Continuous emulsion polymerization of styrene was cond
