The phase behavior of intermediately segregated (N Ο 45) poly(ethylene)poly(ethylethylene) (PE-PEE) diblock copolymers and PE-PEE binary blends are characterized using transmission electron microscopy and small-angle X-ray scattering. Surprisingly, the preparation-dependent, nonequilibrium phase beh

There are three binary pairs in a ternary blend and competition exists among these pairwise interactions owing to the asymmetry of the interaction energies between these binary pairs, which will determine the overall phase behavior of the blend. The influence of molecular weight of the components on
The authors are indebted to Prof. E. Straube (Halle), Prof. K.-F. Arndt (Dresden) and Prof. J. Kressler (Merseburg) for helpful discussions concerning scattering measurements. Thanks to Chr. Sommer for support in static light scattering experiments.
Crystallized chains of nylon 6 lie parallel to the interfaces of the microphase-separated morphology of a nylon 6/PDMS diblock copolymer. Orienting the morphology in the melt using plane strain compression enabled the nylon chain direction to be determined through a combination of transmission elect
