    摘要： A copolymer comprising imidazole ring units having nitrogen at the 1 and 3 positions of the ring; a carbon at each of the 2, 4 and 5 positions of the ring; and radical substituents G1 and G2 carried at the 4 and 5 positions together with a non-imidazole monomer capable of undergoing addition polymerization. In the imidazole, G1 and G2 are each independently selected from cyano, substituents derived from cyano, and substituents which replace cyano. The invention also provides a method for using the co-polymers as a coupling/activator for synthon synthesis.

    摘要： In one embodiment, the invention provides a polymer comprising imidazole ring units having nitrogen at the 1 and 3 positions of the ring; a carbon at each of the 2, 4 and 5 positions of the ring; and radical substituents G1 and G2 carried at the 4 and 5 positions. G1 and G2 are each independently selected from cyano, substituents derived from cyano, and substituents which replace cyano. The polymers formed by at least two of the cyclic imidazole units. In another embodiment, the invention provides new imidazole compounds usable as monomers to form the polymers. In still another embodiment, the invention provides a method for using the polymers as a coupling/activator for synthon synthesis.

    摘要： The invention provides a compound having conjugated double bonds in an acyclic structure formed by Schiff base reaction between an unsaturated aldehyde (RCHO) and diaminomaleonitrile (DE). The compound is a monoalkylated DAMN derivative having one unit of diaminomaleonitrile for every unit of alkyl (RC) derived from the unsaturated aldehyde. The invention also provides a polymer having an acyclic structure and containing monomeric units formed by Schiff base reaction between an unsaturated aldehyde and a diaminomaleonitrile.
