DETERMINATION OF PARTICLE SIZE OF POLYSILOXANE EMULSION AND DISTRIBUTION
有机硅氧烷乳液粒子粒径及其分布的测定

The polysiloxane emulsions were prepared by the copolymerization of methyl cyclo-siloxanes and ethenyl cyclosiloxanes. The ethenyl groups fixed the size of the particles by complexing. The electron micrographs showed that the size of the particles of the anionic emulsion was smaller and more narrowly distributed than that of the cationic one. The stability of the cationic emulsion was improved by adding non-ionic surfactant or by mechanical emulsification.
