Photon correlation spectroscopy (PCS) was used to obtain information on the state of the two phase system following phase separation in the very early stages of vinyl chloride polymerisation.Around a gel phase volume ratio of 103 the particle number appeared constant with the particles growing at constant rate until a sudden decrease in numbers set in at a certain particle size, indicating flocculation. A simple mathematical model is given to account for the observations. From this work and earlier studies a scheme is proposed for the complete life-cycle of the two phase system.
