THERMAL STABILITY OF NETWORKS CONTAINING SILOXANE LINKAGES

Abstract

The thermal stability of elastomers containing siloxane linkages was compared using the technique of chemical stress relaxation in an inert environment. Enchancement of the already high stability of the basic poly(dimethyl-siloxane) silicone rubber by the substitution of hetero groups in and on the main chain was proved. Particularly dramatic was the effect of the m-carborane moiety in SiB-2 elastomers which enhanced the thermal stability of the siloxane chain by more than 100C.
