Novel Thermally Stable and Chemically Resistant Epoxy Polymers Derived from Phenylene Oxides

摘要

Thermogravimetric and differential thermal analysis data are presented for three novel bis-epoxy monomers and formulated coatings derived therefrom. The coatings were insensitive to impact in liquid oxygen and showed excellent resistance to liquid nitrogen tetroxide, concentrated nitric acid, and a variety of organic solvents. All coatings showed excellent adhesion to metals, and oxidation resistance superior to any known commercial epoxy polymer. Thermal resistance was excellent at 500F for periods of at least 500 hours in air. Other data on these novel epoxy polymers are also presented.
