Characterization of Novel Binders Based on Energetic Thermoplastic Elastomers.
Abstract
Beginning in the fall of 1981, a research program was undertaken to develop a series of block copolymers based on novel polyethers. This research is part of the Low Vulnerability Ammunition, LOVA, program of the Office of Naval Research. The principal polymers of interest in this program are the crystalline polyBEMO and polyBAMO, and their thermoplastic elastomers. The most important findings of the past year are: PolyBEMO decomposes endothermally at elevated temperatures, meeting an important LOVA objective of safer compositions; The use temperatures of polyBEMO, polyBAMO, and their block copolymers range from -30 to +75 C. The modulus of the block copolymers is leathery to rubbery, depending on the composition; Processing can be carried out in the range of 80-110 C; and PolyBEMO and polyBAMO are highly crystalline materials. PolyBEMO exhibits more than one crystalline form. Major focus of the research has been to characterize the thermal and physical behavior of these materials.
