Abstract:
A process for producing cured poly(glycidyl nitrate), the process comprising:providing at least one polyol initiator having a hydroxyl functionality of at least three; reacting the at least one polyol initiator with a catalyst to form a catalyst-initiator complex; reacting glycidyl nitrate with the catalyst-initiator complex to form poly(glycidyl nitrate); and cross-linking the poly(glycidyl nitrate) with at least one curative consisting essentially of at least one aromatic diisocyanate, the at least one aromatic diisocyanate having at least one aromatic ring and two isocyanate moieties bonded directly to the at least one aromatic ring, to form cured poly(glycidyl nitrate) having improved stability against de-cure at elevated temperatures.
