Abstract
The present invention discloses monomers of structure (IV) wherein “X” is an alkyl, aryl, or oligoether group, and“R” is an alkyl, aryl, or oligoether group that is chemically bonded to the N1 or N2 position of each of the tetrazole rings. The monomers of the present invention are suitable as binders in energetic compositions.
