ABSTRACT:
Organometallic linear polymers containing metallocene, inorganic units (such as silicon and boron), and acetylenic units which display superb processability, and which are readily converted to a thermoset through the acetylenic groups, yielding high temperature thermosetting polymers and ceramics that exhibit outstanding long-term thermal (high char yield) and magnetic properties and synthesis of these.
