A composition comprising a compound of the formula:
- wherein n is 0-14, y is 1-100, X is either H or NO2, R is an aliphatic, cycloaliphatic, aromatic, or oligoether linker, and R′ is H or a photopolymerizable group, wherein at least one X is NO2;
- and further comprising a compound of the formula:
- wherein n is 0-14, y is 1-100, R is an aliphatic, cycloaliphatic, aromatic, or oligoether linker, and R′ is H or a photopolymerizable group.
