Scaling behaviour in poly(propylene glycol) in the glass transition range,dition to the .-relaxation (stretched exponential decay with stretching parameter ..≈0.40), we observe two relaxation processes not witnessed before by photon correlation spectroscopy. They are attributed to the .′- and .-relaxations and they exhibit similar power law decays. All three processes are

Structural relaxation characteristics of glass-forming polymeric liquids subject to transisent croslation spectroscopy. The dynamics of salt doped polypropylene oxide (PPO) have been investigated in relation to induced local structural ordering. It is accomplished by forming complexes of NaCF.SO.-PPO in which the cations act as transient cross-links between chains. The amount of cross-links depen

Investigations of self- and tracer diffusion in poly(ethylene oxides) and in blends of poly(dimethyon coefficients of both components in the blend of poly(ethylmethylsiloxane)/poly(dimethylsiloxane). In the melts of lower molecular weight poly(ethylene oxide) aggregation behaviour as reported in literature (VA Sevreugin et al. (1986) Polym 27:290) within the time scale of the experiment could be

Static and dynamic scattering at the microphase separation transition in block copolymers,n spectroscopy (PCS) and dielectric spectroscopy (DS). The static structure of concentration fluctuations is found to deviate from the Gaussian coil assumption in a temperature regime above the microphase separation transition (MST). The dynamic experiments in this temperature regime test concentrat
