Transition behavior of poly(vinylidene fluoride)/poly(ethyl methacrylate) blends

Abstract

Abstract Previous work has shown evidence that PMMA and PEMA are miscible with PVF 2 . The present paper examines in detail the behavior of PEMA/PVF 2 blends by thermal analysis and dynamic mechanical testing. All transitions and relaxations are affected by blond composition but in a complex manner owing to the crystallization of PVF 2 from blends rich in this component. Inadequacies of the simple two‐phase picture of semi‐crystalline polymers is believed responsible for some of the transitional behavior observed here. The melting point depression observed for PVF 2 was found to be consistent with an exothermic heat of mixing for this pair comparable in value to that found for PPMA/PVF 2 /All evidence here are consistent with the previous conclusion of miscibility for these systems.
