Mass Spectrometric Thermal Decomposition and Ultraviolet Irradiation Studies of Some Azido and Nitrato Polymeric Binders.
Abstract
Thermal decomposition studies were conducted on AZOX and AMMO homopolymers and on 50-50% BAMO-AZOX and 50-50% BAMO-AMMO copolymers. Decomposition was initiated at approximately 120 C, with an activation energies for the materials approximately 170 kJ/mol. The primary mechanism for the decomposition is the release of molecular N2. Backbone decomposition occurs at temperatures above 150 C with thermal destruction of the three-carbon chain. A thermal decomposition study of a new copolymer consisting of an azido (BAMO) and nitrato group decomposition of a new amino nitro ring compound, C6 H8 N8 012, indicated No2 release with ring stability. Qualitative UV irradiation experiments at 2540 A and 3660 A wave lengths then were conducted on AZOX and AMMO homopolymers and 50-50% BAMO-AMMO and 50-50% BAMO-AZOX copolymers. Upwards of 25% of the polymetric N2 was released with considerable cross-linking. The samples changed from viscous liquids to gummy, rubbery semi-solids. The irradiated samples were maintained for a number of weeks under ordinary atmospheric conditions as well as under vacuum without any indication of autocatalysis. (Author)
