    摘要： A cyclotrisiloxane represented by the general formula (1): ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 may be the same or different and are each an alkyl group of 1 to 3 carbon atoms and X is a cyclohexyl group or an alkyl group expressed by the formula:--C.sub.n H.sub.2n+1where n is an integer of 4 to 15. The cyclotrisiloxane is useful as an intermediate for producing silicone oils and silicone rubbers, and the obtained silicone oils and silicone rubbers are excellent in lubricity.

    摘要： A chain organopolysiloxane is obtained by polymerizing a fluorine-containing cyclotrisiloxane of the general formula: ##STR1## (wherein R.sup.1 is a monovalent hydrocarbon group, and Rf is a perfluoroalkyl group or perfluoroalkyl ether group)in the presence of a lithium silanolate catalyst, silylating the resulting polymerization product, and treating the silylated product at a temperature of not lower than 100.degree. C. under a reduced pressure of not higher than 10.sup.-1 mmHg to remove volatile components therefrom. The organopolysiloxane is essentially free of volatile low-molecular siloxanes. Therefore, the chain organopolysiloxane can be used without the problems which might arise from the volatile low-molecular siloxanes, such as evaporation of low-molecular siloxanes from a cured rubber product with the result of electrical-contact troubles.
