![]() Monomer added duting Stages II and III only serves to increase the size of the existing particles. ![]() Whatever the nucleation mechanism the final particle size of the latex is determined duting Stage I, provided no additional particle nucleation or coalesence occurs ia the later stages. The diethylene glycol monoalkyl ether group of CiEj enhances the latex stability and the CiEj more effectively stabihses the styrene microemulsion and subsequent polymerisation compared with CiOH cosurfactants used as a comparison. A smaller number of latex particles nucleated than there were microemulsion droplets initially present. The pseudo three-component phase diagram, macroemulsion, microemulsion and lamellar gal phases, was constructed for the cosurfactants. Sodium dodecyl sulphate was used as a surfactant. Diethylene glycol monoalkyl ether was used as a cosurfactant in the formation of an oil-in-water styrene microemulsion.
