Patent ID: 6861501

Claim:
A process for producing cured poly(glycidyl nitrate), comprising: providing at least one multi-functional alcohol initiator having a hydroxyl functionality of at least two; reacting the at least one multi-functional alcohol 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 comprising at least one aromatic polyisocyanate having a functionality greater than two, the at least one aromatic polyisocyanate having at least one aromatic ring and having, on average, more than 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.
