TLDR
In this article, the dielectric β relaxation of polyvinyl chloride has been studied in the ranges of temperature, pressure and frequency, 296 to 353 K, 1 × 105 to 3 × 108 N m 2 and 1 to 105 Hz.Abstract:
The dielectric β relaxation of polyvinyl chloride has been studied in the ranges of temperature, pressure and frequency, 296 to 353 K, 1 × 105 to 3 × 108 N m–2 and 1 to 105 Hz. Detailed results are discussed in terms of current concepts of the α, β and (αβ) relaxations which occur in amorphous polymers and in small molecule glass forming systems.read more

Classification of secondary relaxation in glass-formers based on dynamic properties.
K. L. Ngai,Marian Paluch +1 more
TL;DR: This work identifies the class of secondary relaxations that bears a strong connection or correlation to the primary relaxation in all the dynamic properties and proposes that only these should be called the Johari-Goldstein beta-relaxation.

The dielectric response of simple organic glass formers
TL;DR: In this article, the complex dielectric permittivity e ν above and below the glass transition temperature, T g, was investigated in the frequency range 10 −3 ÂHz 9 Â Hz and a quantitative line-shape analysis was carried out including both processes by applying the Williams-Watts (WW) approach.
