A method of increasing the thermostability of organopolysiloxanes and compositions containing the same comprising introducing into organopolysiloxanes and compositions based on them 0.01 to 10 weight parts of a polyethynylpyridine or synergistic mixtures of 0.01 to 10 weight parts of a polyethynylpyridine with 1 to 10 weight parts of metal salts or an oxide of a metal per 100 weight parts of organopolysiloxane. The resulting thermostable organopolysiloxanes and compositions based on them find application in aviation, ship building industry, rocketry, and in other branches of the industry. |
