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. Differential scanning calorimetry (D
In the present study, ethylene/vinyl alcohol (EVAL) copolymers with different hydroxyl contents were melt mixed with styrene/maleic anhydride (SMA) copolymers. These two copolymers have functional groups capable of reacting intermolecularly, giving stable products. All EVAL copolymers were prepared
