Abstract
1-Methyl-2,5-bis[1-(4-phenylurazolyl)] pyrrole was prepared from the reaction of 4-phenyl-1,2,4-triazoline-3,5-dione with N-methylpyrrole in methylene chloride solution. This compound was converted to its potassium dianion salt upon reaction with potassium hydroxide in absolute ethanol. The reaction of this dianion salt with excess methyl iodide in dimethyl sulphoxide gave the methylated adduct in high yield. Polymerizations of this dianion salt with 1,2-dibromoethane, 1,2-diiodoethane and 1,4-diiodobuthane were performed in dimethyl sulphoxide and led to the formation of new polymers. Some structural characterization and physical properties of these novel polymers are reported. © 1998 SCI.
