Abstract: With a 'push' plastometer, the effect of NO₂^-, ClO₃^-, BrO₃^-, and CrO₃ on the stability of poly(trifluorochloroethylene) (I) in the relation to the temp. suitable for good workability was described. The addn. of 0.1% KBrO₃ + 0.1% NaNO₂ to I had an optimum effect on the thermal degradation of I; good workability was possible at 300-40°. By this stabilization, the mech. properties of I are improved and the elec. properties are not impaired. Of the metals, Cu has a catalytically detrimental effect and Al, Zn, Fe, and Cr an unfavorable effect on the rate of decompn. of I.
