ABSTRACT:
Active polymeric matrices, xerographic elements and a process for obtaining the monomer and polyester material by reacting an aldehyde of a desired polycyclic aromatic compound with a dicarboxy acid ester in the presence of a base to obtain an unsaturated dicarboxyester intermediate; cyanating the intermediate in the presence of alcohol to obtain a saturated B-cyano monocarboxy acid ester which is hydrolyzed to the .alpha., .beta. dicarboxy intermediate and then esterified to obtain the .alpha., .beta. dicarboxy ester monomer. This monomer is catalytically polymerizable with a polyhydroxy alcohol such as a glycol to obtain the polyester.
