Abstract
A method is provided in which PGN is end-modified in a process using a single solvent. The resulting end-modified PGN may be stably crosslinked using aliphatic polyisocyanates. Further provided are methods of producing energetic compositions comprising PGN which has been end-modified in a process using a single solvent. Such energetic compositions may be stably crosslinked using aliphatic polyisocyanates.
