Abstract : Significant reports covering the period since 1960 were selected for this study with reference to relevant earlier works. Recent Government-sponsored research and development (R&D) in high temperature elastomers has been directed along two lines: (1) new polymer synthesis and (2) evaluation of compounds to improve the thermal stability of current elastomers. Progress has been made in each of these areas. Large groups of inorganic and semi-inorganic polymer systems were evaluated. Systems included silazanes, siloxanes, and fluorocarbons.
