|Abstract||A series of coumarins were reacted with methacrylate or styrene derivs. to form new olefinic coumarin monomers that were polymd. using 2,2'-azobisisobutyronitrile. These polymers were highly insol. in org. solvents and displayed good thermal stability with glass-transition temps. 70-130Â°. Luminescence studies on some of the coumarin-contg. polymers showed some fluorescence (Î¦F around 0.1). Some of the newly prepd. coumarins and benzocoumarins were reacted with azo dyes to form mixed coumarin-azo dye monomer precursors. These compds. were further reacted to prep. acrylic monomers which were then polymd. [on SciFinder(R)]|
