Abstract
A polyvanadiosiloxane being a polymer of which the main chain skeleton consists of Si-O bonds and V-O bonds, characterized by side chains directly attached to the silicon atom being at least one organic group selected from the group consisting of a lower alkyl group, phenyl group, fluoroalkyl group, nitrile group and vinyl group, the vanadium atom being attached to the silicon atom through the oxygen atom and no organic side chain group directly attached to the vanadium atom being present in substance; and a process for the production of a polyvanadiosiloxane which comprises reacting an oily polysiloxane having the main chain skeleton consisting of units of ##STR1## wherein R.sub.1 and R.sub.2 may be the same or different and stand for a lower alkyl group, phenyl group, fluoroalkyl group, nitrile group or vinyl group, and a vanadium compound by heating at a temperature of 450.degree. C. or less under conditions capable of forming a complex of the vanadium compound.
