Abstract
PURPOSE: To produce a polyvanadiosiloxane having excellent heat resistance, flame retardancy and cold resistance, by reacting with heating, a specified oily polysiloxane, a V compound and a complexing agent.
CONSTITUTION: (A) An oily polysiloxane, average polymerization degree 5W5,000, viscosity ≤1×106 cst, having a main chain structure consisting of units represented by the formula, wherein R1 and R2 are same or different and are each a lower alkyl, phenyl, a fluoroalkyl, nitrile or vinyl, is mixed with (B) a V compound such as VCl4 or Na(VOCl4) and (C) a complexing agent for said component B, such as tetrahydrofuran or pyrone. The resulting mixture is heated to below 450°C, pref., 200W350°C to bond part of the Si atoms to V atoms through O atoms.
USE: Seals, gaskets, diaphragms, etc.
