A series of poly(methyl methacrylate-co-methacrylic acid) (PMMA-co-MAA) random coplymers ranging in MAA content from 0-15 mole% have been synthesized and blended with poly(vinylidene fluoride) (PVDF).  Using polarized optical microscopy, the spherulitic growth rate of the PVDF in teh blends was determined.  The results showed that at low MAA comonomer contents (<5 mole%), a significant decrease in the spherulitic growth rate of the PVDF occurred, while at higher MAA contents, the growth of the PVDF spherulites in the blend approached that of pure, unblended PVDF.  These results suggest that while the hydrogen-bonding of the PMMA-co-MAA blend component initially produces a greater intermolecular interaction with PVDF, eventually, the intramolecular interaction of the higher MAA content copolymers causes the PMMA-co-MAA to interact less with teh PVDF blend component.
