SYNTHESIS OF γ-SUBSTITUTED-PROPYLCYCLOTETRASILOXANES AND THEIR EMULSION COPOLYMERIZATION WITH OCTAMETHYLCYCLOTETRASILOXANE*

Received Date: 22 April 1983

Four γ-substituted-propylcyclotetrasiloxanes have been synthesized. Emulsion copolymerizations of these cyclosiloxanes with octamethylcyclotetrasiloxane have been carried out both in cationic and anionic emulsion systems. By way of these reactions, stable emulsions of organosilicon polymers which contain carbonfuctional groups such as γ-hydroxypropyl, γ-acetoxypropyl and γ-chloropropyi have been obtained. The effects of temperature, catalyst and the amount of γ-substituted-propylcyclotetrasiloxanes in emulsion copolymerizations have been studied.
