## Abstract The complex polymorphic behavior of syndiotactic polystyrene (sβPS) in meltβcrystallized samples is altered by blending with poly (2,6βdimethylβ1,4βdiphenylene oxide) (PPO). In particular, to render the beta form in these blends, starting with samples containing the Ξ± or Ξ³ froms, requir
Differential scanning calorimetry (DSC) and X-ray diffraction analysis were performed to study the multiple melting behavior and crystal forms of neat syndiotactic polystyrene (s-PS) in comparison with its miscible blends with amorphous atactic polystyrene (a-PS) or poly(2,6-dimethyl-p-phenylene oxi
