The objective of the work covered in this report is to prepare hybrid polymers having good thermal, oxidative, and hydrolytic stability, plus good mechanical properties in the vicinity of 900 to 1000F. Hybrid polymers in this case refers to polymers prepared from organometallic compounds, which are combinations of organic and metal radicals. During the course of this work, 14 new difunctional monomers and polymers were prepared. All of these compounds are amenable to polymerization but due to the time-consuming nature of the synthetic work and the difficulties encountered with characterization of the polymerized products, only a few of these compounds were subjected to cure studies. The monomers contain various combinations of carboranes, ferrocenes, and siloxane groups.
