Thermoplastic Elastomers as LOVA Binders: End of the Year Report for Contract N00014-85-K-0080

摘要

For the first time main chain liquid crystalline polymers have been synthesized. Both polyalkylene oxides and polyfluoroformals (NSWC) have been incorporated as spacers. Mesophase transitions were designed and found to occur at processing temperatures. Structural orders have been shown to exist above clearing temperature by both rheological and spectroscopic measurements. Acid dopolymerizable trioxanne dioxolane hard segments have been synthesized with adjustable melt temperatures from 70 C to 138 C. Synthesis of completely acid depolymerizable LOVA TPE binders have been scaled up by Olin for sampling to China Lake and Aberdeen.
