Phase separation in quenched noncrystalline poly(vinylidene fluoride)/poly(methyl methacrylate) blends
Abstract
The dielectric characterization was carried out in poly(vinylidene fluoride) (PVDF)/poly(methyl methacrylate) (PMMA) blends quenched from the melts. In the quenching of 60/40 PVDF/PMMA, the phase separation between the PVDF phase and the mixed PVDF-PMMA amorphous phase was observed in apparently completely noncrystalline blends. The dielectric behaviors for this PVDF phase separated were the same as those of the PVDF crystal-amorphous interphase. The PVDF phase/mixed amorphous phase separation was explained by forming incipient crystallites of PVDF. © 1992 The Society of Polymer Science, Japan.
