Abstract
Samples of silicone elastomeric materials based on linear ladder block copolymers containing linear polydimethylsiloxane and ladder phenylsilsesquioxane molecular units have been obtained and investigated. It has been shown that the use of such block copolymers of the brands Lestosil N and Lestosil SM improves the heat resistance of the obtained vulcanizates up to 350°C for a long time.
