## Abstract A discrete relaxation spectrum using a small number of modes is derived to describe the relaxation behaviour of monodisperse polystyrene melts. Attention is focused on keeping the physical meaning of the relaxation times. Therefore, molecular dynamics theories are used in the terminal,
## Abstract From highβresolution dielectric spectroscopy measurements on 1,4βpolybutadiene (1,4βPB), we show that in addition to the structural Ξ±βrelaxation and higher frequency secondary relaxations in the spectra, a nearly constant loss (NCL) is observed at shorter times/lower temperatures. The p
