    Structural Development During Thermal Fractionation of Polyethylenes

    In this study, the stepwise isothermal crystallization or thermal fractionation of Ziegler—Natta and metallocene based polyethylenes (ZN-PE and m-PE) with two kinds of branch lengths (ethyl and hexyl) and bran...

    Small-Angle Scattering Investigations of Crystalline Blend Morphologies of Poly(ε-Caprolactone) (PCL)/Polycarbonate (PC) Blends

    Crystalline morphologies of poly(ε-caprolactone) (PCL) and deuterated polycarbonate (PC) blends in both the semicrystalline/amorphous state and semicrystalline/semicrystalline state were probed by small-angle ...

    The Volume Fraction Profile of Terminally Adsorbed Polymers

    We have used neutron reflectivity to measure the concentration profile of carboxylic acid-terminated polystyrene at the liquid/solid interface. Two isotopic systems were studied: (1) deuterated polystyrene (DP...

    X-Ray Reflectivity and Fluorescence Measurements From Polystyrene-Co-Bromostyrene/Polystyrene Interfaces

    X-ray fluorescence using synchrotron radiation at glancing angles of incidence was used to measure interface widths for the highly immiscible polymer blend system polystyrene/polybromostyrene (PS/PBrxS, with brom...
