Figure 17.8 shows SEM pictures of (a) PVC particles prepared by swelling a pre-emulsion of Y-droplets with VC followed by polymerizaticai, and (b) 17 pm monodisperse PVC particles made by a seed process (Norwegian Patent Application No. 961625). In two recent papas, Saethre [95] and Mpik et al. [96] have studied the various parameters which influence the formation of VC miniemul-sions, and the particle size and size distribution of the final latex. Some of their most interesting results and conclusions may be summarized as follows.
