摘要： A process is provided in which at least one polyol having a hydroxyl functionality of at least three, preferably four, serves as a polymerization initiator. The polyol initiator is optionally, although preferably, reacted with a catalyst to form a catalyst-initiator complex, which is then used in the polymerization of glycidyl nitrate. The resulting polyfunctional poly(glycidyl nitrate) has a functionality substantially equivalent in number to the hydroxyl functionality of the polyol. The poly(glycidyl nitrate) is cross-linked with at least one aromatic diisocyanate having at least one aromatic ring and two isocyanate moieties bonded directly to the at least one aromatic ring. Examples of the aromatic diisocyanate include toluene diisocyanate, phenylene diisocyanate, and/or methylene di-p-phenylene diisocyanate.
