A dielectric study of poly(ethylene‐co‐vinyl acetate)–poly(vinyl chloride) blends. II. Loss curve broadening and correlation parameters

Abstract

Abstract Normalized dielectric loss curves for blends of PVC with an EVA copolymer containing 70% vinyl acetate showed significant broadening with increasing PVC content. In conjunction with phase separation studies it was concluded that increasing loss curve broadness correlated with increasing tendency toward phase separation. Calculation of correlation parameters for the blends revealed differences in intermolecular correlations with blend composition.
