THE THERMAL STABILITY OF PHENYL CONTAINING SILICONE RUBBERS.
Abstract
A comparison has been made between the thermal stabilities of phenyl methyl silicone rubbers cross-linked by organic peroxides and by high energy irradiation. The large quantities of peroxide required to produce practical levels of cure, lead to reactions detrimental to heat stability and the resulting vulcanisates offer no advantages over peroxide-cured methyl vinyl polymers. Such undesirable effects can be eliminated by the use of irradiation, which, combined with the superior oxidation resistance provided by the phenyl groups producess an elastomer of outstanding heat stability.
