Popis: Poly(coumarin ethylenes/propylenes) were prepared by reacting 4-methyl-7-hydroxy- and 4-phenyl-7-hydroxy-coumarins with 1,2-dichloroethane and 1,3-dibromopropane in the presence of aluminum chloride under Friedel-Crafts reaction conditions by varying molar proportion of the catalyst, neat reaction and use of solvent. All poly (coumarin ethylenes/propylenes) were characterized by elemental analysis, IR spectral studies, number average molecular weight determination by non-aqueous conductometric titration, viscosity studies, and thermogravimetry.
