ABSTRACT:
A process for producing a heat-resistant and moisture-resistant polyborometallosiloxane, which comprises adding a metal compound and a compound capable of easily forming a complex with the metal compound to an organoborosiloxane, the metal in said metal compound being at least one member of the group consisting of Ti, Zr, V, P, Al, Fe, Cr, Co, Ni, Ge, Sn, As, Mg, Pb and Sb; and heating the resulting mixture to a temperature of 550.degree. C. or lower to bond the metal atom to the silicon atom and/or the boron atom through an oxygen atom.
