We resolved the longtime enigma in emulsion polymerization of styrene with K2S2O8 by showing the fact that hollow polystyrene particles were successfully prepared by heat treatment in the emulsion state.

Nonionic Emulsifier

Here is analysed how suitable are the most frequently used empirical relations for description of drop size distribution. On a representative set of emulsifying experiments is demonstrated how suitable in the three-parametric logarithmic normal distribution according to Cohen and distribution according to Espenscheid-Kerker-Matijević. For these functions are proposed methods of parameter estimation suitable for their determination from the random sample of emulsion droplets. The fittnes of testing functions is discussed briefly.
