Thermal behaviour and morphology of blends of poly(ethylene oxide) (PEO) and poly(styrene-co-maleic anhydride) (SMA) prepared by the coprecipitation technique were studied by means of di β erential scanning calorimetry, optical microscopy and thermogravimetry. SMA containing 25 wt% maleic anhydride (
The phase behaviour of poly(styrene-co-methyl methacrylate) blended either with poly(styrene-co-acrylonitrile) or poly(styrene-co-maleic anhydride) was studied. The blends were found to be miscible in certain ranges of copolymer compositions. Light scattering and DSC measurements showed them to phas
