## Abstract Dynamic viscoelastic properties of blends of poly(methyl methacrylate) (PMMA) and poly(styreneβ__co__βacrylonitrile) (SAN) with various AN contents were measured to evaluate the influence of SAN composition, consequently Ο parameter, upon the melt rheology. PMMA/SAN blends were miscible
Isotactic, atactic, and syndiotactic poly(methyl methacrylates) (PMMAs) (designated as iPMMA, aPMMA, and sPMMA) were mixed with poly(styrene-co-phydroxystyrene) (abbreviated as PHS) containing 15 mol % of hydroxystyrene separately in 2-butanone to make three polymer blend systems. Differential scann
