The miscibility of C 60 -containing poly(methyl methacrylate) (PMMA-C 60 ) with poly(vinylidene fluoride) (PVDF) was studied. Two PMMA-C 60 samples containing 2.6 and 7.4 wt % C 60 were found to be miscible with PVDF based on single glass transition temperature criterion and melting point depression

Abstract
A series of coumarins were reacted with methacrylate or styrene derivatives to form new olefinic coumarin monomers that were polymerized using 2,2′‐azoisobutyronitrile (AIBN). These polymers were highly insoluble in organic solvents and displayed good thermal stability with glass‐transition temperatures between 70 °C and 130 °C. Luminescence studies on some of the coumarin‐containing polymers (CCPs) showed some fluorescence (Φ~F~ around 0.1). Some of the newly‐prepared coumarins and benzocoumarins were reacted with azo dyes to form mixed coumarin‐azo dye complexes. These mixed complexes were further reacted to prepare acrylic monomers and polymerized using AIBN. These polymers were thermally stable and poorly soluble in organic solvents.
