EVA was blended with phenoxy over the whole range of composition using a twin-screw Brabender. Two-phase separation caused by EVA crystallization was observed in the EVA-rich blends and the dispersed domain of EVA was not clearly shown in the phenoxy-rich blends.

✦ Synopsis
To obtain a correlation among structure-morphology-mobility-compatibility properties of poly(ethylene-co-vinyl acetate) (EVA)/poly(vinyl acetate) (PVAc) blends, we have used scanning electron microscopy and solid-state nuclear magnetic resonance in our investigations. The results are discussed in terms of blends, component dispersion, plasticization effect, and domain mobilities to acquire a response of the correlation between structural properties.

The rheological studies of the poly(vinyl chloride-co-vinyl acetate) and poly-(styrene-co-acrylonitrile) blends were performed by a Brabender Rheotron at three different temperatures and also at different shear rates. Flow curves of the blends at different temperatures were drawn. The flow behavior
## SYNOPSIS The grafting preference of vinyl acetate onto the methine carbon of poly(viny1 alcohol) (PVOH) versus the acetate group of poly(viny1 acetate) (PVAc) was determined as part of an attempt to prepare novel branched PVOH from partially hydrolyzed PVAc. The results showed long chain grafti
