Journal ArticleDOI
A complex plane representation of dielectric and mechanical relaxation processes in some polymers
S. Havriliak,S. Negami +1 more
TL;DR: In this paper, it was shown that the complex deformation of the same data can be represented by a function of same form but with different values for the constants, which can be interpreted as the decay of the distortion with time of the removal of stress field.
Journal ArticleDOI
A complex plane analysis of α‐dispersions in some polymer systems
S. Havriliak,S. Negami +1 more
TL;DR: In this paper, the authors measured and analyzed the complex dielectric behavior of the α-dispersions for five polymers [i.e., polycarbonate and polyisophthalate esters of bisphenol A, isotactic poly-(methyl methacrylate), poly(methyl acrylate) and a copolymer of phenyl methacellitrile] and found that the usual methods of analysis cannot be used to represent the data.
Journal ArticleDOI
On the equivalence of dielectric and mechanical dispersions in some polymers; e.g. poly(n-octyl methacrylate)☆
S Havriliak,S. Negami +1 more
TL;DR: In this paper, the authors compared the dielectric and viscoelastic data of poly(n-octyl methacrylate) and showed that the shape of the relaxation curve changes with the number of dispersion samples.
Journal ArticleDOI
On the equivalence of dielectric and mechanical dispersions in poly(n-hexyl methacrylate)
S Havriliak,S. Negami +1 more
TL;DR: In this paper, the authors constructed a mechanical analogue of the complex polarizability for comparing dielectric dispersion data, and the parameters used to represent the relaxation data of poly(n-hexyl methacrylate) in two forms were determined.
