HIGH DENSITY, HIGH TEMPERATURE BINDERS FOR SOLID PROPELLANTS.
Abstract
Chemical purification of perfluorooxydipropionyl fluoride has resulted in good yields of high purity monomer for photopolymerization reactions. Extensive photopolymerization studies were conducted on perfluorooxydipropionyl fluoride to analyze the factors which influence molecular weight, extent of branching, and functionality. A variety of curing reactions have been carried out on model compounds and polymer samples using epoxides, oxazolines and oxetanes. A high yield, room temperature catalytic trimerization of perfluoroalkanonitriles was discovered under this contract. A variety of possible catalysts have been screened, and the most active of these, tributyl antimony oxide, was used to prepare perfluoroalkyl triazines for thermal and hydrolytic stability studies. Polymer samples have been evaluated in the presence of aluminum and ammonium perchlorate to determine their compatibility with propellant mixtures. (Author)
