摘要
This invention is directed to stabilizing additives that contain at least one platinum complex, with the complex including a carbene group. The stabilizing additives make it possible to improve the resistance to decomposition of silicone elastomers under high temperatures. The additive can be used in a polyorganosiloxane composition intended for the production of a silicone elastomer with either crosslinks at high temperature under the action of organic peroxides or crosslinks at ambient temperature or with heat by polyaddition reactions in the presence of a metal catalyst.
