ABSTRACT:
Thermally stable thermosets are formed from novel linear polymer containing acetylenic units and a random distribution of organotransition metal complexes, siloxane, boron, and/or carborane-siloxane units formed by crosslinking of the linear copolymers through the acetylene units in the polymer backbone. The thermosets can be used as structural components in high temperature and oxidizing environments or as pyrolytic precursors to metal containing ceramics, ceramic films and fibers having enhanced strength and toughness with superior mechanical, optical, electrical and/or magnetic properties.
