STABILIZATION OF POLYSILOXANES BY ANTIOXIDANT ADDITIVES.
Abstract
It was established that the most effective antioxidation additive to polyimethyl-siloxane oil (PMS-100) at the temperatures 250, 300 and 350C, proves to be 1.4-dimezidin-anthraquinone, the introduction of which in the amount of 0.5% improves the thermooxidation stability of PMS-100 at 300C by a factor of 16 and at 250C by a factor of 44. It was shown, that for some additives, the effectiveness of action with increasing concentration goes through a maximum, and the use of them above 3.0% is not feasible. (Author)
