Abstract: SILYLORGANOMETALLOCENES SELECTED FROM THE CLASS OF (A) POLYMERS OF THE FORMULA,

(C5Q5)M(C5Q4)-CO-NH-R"-SI(-(R)A)-O((3-A)/2)

(B) COPOLYMERS HAVING UNITS OF THE FORMULA,

(R)B-SI-O((4-B)/2)

AND AT LEAST ONE UNIT OF (A), AND (C) DISILOXANES OF THE FORMULA,

((C5Q6)M(C5Q4)-CO-NH-R"-SI(-R)2)2-O

WHERE R IS A MONOVALENT HYDROCARBON RADICAL, R" IS A DIVALENT HYDROCARBON RADICAL, AND(C5Q4)M(C5Q5) IS AN ORGANOMETALLOCENE, WHERE Q IS SELECTED FROM HYDROGEN, AN ELECTRON DONATING ORGANIC RADICAL, AND AN ELECTRON WITHDRAWING ORGANIC RADICAL AND M IS A TRANSITION METAL, A IS A WHOLE NUMBER EQUAL FROM 0 TO 2 AND B IS A WHOLE NUMBER EQUAL FROM 0 TO 3. THESE SILYLORGANOMETALLOCENES ARE USEFUL AS ANTIOXIDANTS FOR ORGANOPOLYSILOXANE FLUIDS UNDER EXTREME OXIDATION CONDITIONS.
