Interrelation of phase and relaxation behavior in polymer blends and block copolymers with crystalltudied, and their interaction and coupling was found manifested in formation of various non-equilibrium morphologies and abnormal increase of crystallization rate at the separation boundary. The morphology is determined by the ratio of demixing and crystallization rates.

Field-induced structure conversions in PVDF,ferent conformations and crystalline structure are investigated in dependence on the poling conditions. By means of modified wide angle x-ray methods it is possible to separate individual effects from each other.

Broadband dielectric spectroscopy on the molecular dynamics in polymer model-systems: polyphenylmet the ratelimiting quantity and hence determine the molecular dynamics. In the case of poly(cis-1,4-isoprene) the molecular dynamics of the linear and the starbranched polymer are compared. Two relaxation processes, a segmental and a normal mode, are observed. Its dependence on temperature, molecular weight, and the chemical structure is discussed.

Contour-length fluctuation of polymers: NMR experiments and statistical physics,ce of longitudinal displacements and contour-length fluctuation as fundamental mechanisms. On this basis a segment orientation correlation function has been established which describes and explains a broad variety of dependences and phenomena. This concept involves a new interpretation of the Doi-Ed

Dispersive and non-dispersive transport processes in polymers,harge carrier motion in a random solid is discussed. While under realistic conditions positional disorder will not give rise to dispersive behavior on the time-scale of a carrier transit, both E-hopping and multiple trapping do so because of energetic relaxation of the carriers within the density of

Hypersonic properties of a smectic side chain polymer liquid crystal with a PA main chain,nsitions at hypersonic frequencies. In contrast to classical liquid crystals the polymer materials show at both transitions a significant coupling between the static order parameter and the square of the elastic strain ɛ.. The inverse shear stiffness constants do not diverge. All elastic constants b
