Abstract
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.
