The kinetics of the microphase separation transition in a diblock copolymer of polystyrene/polyisoprene was studied with time-resolved small-angle X-ray scattering. Using synchrotron radiation it was possible to determine the structure factor in time

Analysis of measurements of the static scattering function by electron and X-ray diffraction, of the dynamic scattering law by neutron scattering, and of infrared and Raman spectra points at the important role of twin helix-reversal defects for the m

The self-diffusion of diblock copolymers of polystyrene/cis-1,4-isoprene and polyisoprene homopolymers is studied using field gradient nuclear magnetic resonance. The block copolymers are shown to go through their order-to-disorder transition (ODT) a

Segmental dynamics in the disordered regions of partially crystalline polyethylene was investigated by quasielastic incoherent neutron scattering. Experiments provide evidence for the peculiar nature of the disorderd regions, where the motion is rest

Static and dynamic light scattering was applied in a comprehensive study of the different modes of relaxatory motion in polystyrene-dioxane mixtures, comprising the whole range of different compositions from dilute solution to plasticized melts. For

The microphase separation transition (MST) in a series of diblock copolymers of polystyrene/cis-1,4-isoprene of low molecular weight (10500-20800) and various compositions is studied using small-angle X-ray scattering (SAXS) and dielectric spectrosco
