High Temperature Ceramics Derived From Linear Carborane-(Siloxane or Silane)-Acetylene Copolymers

摘要

This invention relates to a new class of novel inorganic-organic hybrid polymersthat are formed from linear inorganic-organic hybrid polymers of varying molecular weight. These new high temperature oxidatively stable thermosetting polymers are formed from linear polymeric materials having repeat units that contain at least one alkynyl group for cross-linking purposes and at least one bis(silyl or siloxanyl)carboranyl group and wherein the carborane content of the thermosets can be varied. These novel thermosetting polymers can be further converted into ceramics at elevated temperatures. jg.
