Abstract

PURPOSE: To enable the ring opening polymerization of cyclic organosiloxane compound extremely easily and in high yield, and to obtain a poly (organosiloxane) directly, by bringing a specific cyclic organosiloxane compound into contact with plasma.
CONSTITUTION: A cyclic organosiloxane compound shown by the formula I (R1 and R2 are organic substituent and partially inorganic substituent; n is positive integer of 2W12) preferably compound shown by the formula II or III, is brought into contact with plasma to give a poly (organosiloxane). R1 and R2 are preferably (al)alkyl, aryl, (al)alkoxy, alacyl, etc. Preferably plasma is generated under reduced pressure 0.0001W100Torr at low impressed voltage 20W1,000 watt to carry out the reaction.
