Phase behavior of blends of polycarbonate with partially miscible polymers

摘要: Phase behavior of blends bisphenol A polycarbonate (PC) with polystyrene (PS), poly(styrene-co-acrylonitrile) (SAN), poly(acrylonitrile-butadiene-styrene) (ABS), poly(methyl methacrylate) (PMMA), poly(ethylene terephthalate) (PET), and poly(butylene (PBT) has been investigated. Blends were prepared by screw extrusion solution casting weight fractions PC in the varying from 0.90 to 0.10. From phase diagram blends, it appears that PS, SAN, ABS, PMMA, PET, PBT dissolve more PC-rich than does PS-, SAN-, ABS-, PMMA-, PET-, PBT-rich phases. Also, measured glass transition temperature (Tg) screw-extruded solution-cast compatibility increases compositions compositions. Composition-dependent values polymer-polymer interaction parameters (g12) various calculated found be 0.034 0.053 for equal weights each polymers PC.
