Abstract

PURPOSE: To prepare a polymetallosiloxane having excellent heat resistance and being able to maintain elasticity even at a high temperature, by adding a metallic compound other than V compounds and a complexing agent to a specific oily polysiloxane and heating the mixture.
CONSTITUTION: To an oily polysiloxane having a main chain skeleton consisting of units of formula (A), where R1 and R2 may be the same or different and are lower alkyl, phenyl, fluoroalkyl, nitrile or vinyl, an average polymerization degree of 5W5,000, and a viscosity of one million cst or less, a metallic compound other than V compounds [e.g. Cr(CH2COCH2COCH3)3] (B) and a complexing agent for component B (e.g., tetrahydrofuran) (e) are added, and the mixture is heated at 450°C or lower in an atmosphere of an inert gas or oxidizing gas to bond part of Si of component A with a metal atom via an oxygen atom.
