Isotactic, atactic, and syndiotactic poly(methyl methacrylates) (PMMAs) (designated as iPMMA, aPMMA, and sPMMA) with approximately the same molecular weight were mixed separately with poly(styrene-co-acrylonitrile) (abbreviated as PSAN) containing 25 wt % of acrylonitrile in tetrahydrofuran to make
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
