TL;DR: In this paper, a mixture of diglycidyl ether of bisphenol A (DGEBA) with γ-valerolactone (γ-VL) 2:1 (mol/mol) with different organically modified clays were cationically copolymerized in the presence of scandium, ytterbium or lanthanum triflates as initiators.

TL;DR: In this article, a critical assessment of the application of thermally stimulated discharge (TSD) measurements to epoxy resins is presented. But, whilst the method can be used for monitoring cure, there are problems concerned with the detailed interpretation of the TSD data, and the observed TSD peaks are complex and associated with charge migration coupled with dipolar reorientation.

TL;DR: In this article, the effects of various fillers on the breadth and temperature dependence of the vibration damping characteristics of a filled and crosslinked polyurethane elastomer are explored.

TL;DR: In this paper, the authors explored the way in which the data obtained from the dielectric study (reported in Part II of this 3-part series of articles), can be related to the mechanical strength of the bonded structure.

TL;DR: In this article, the variation of the dielectric constant and the tribo-electric coefficient for a series of pigmented, melt-mixed, polymer materials are presented and it is shown that in certain situations, a correlation may exist between the Dielectric Constant and the observed triboelectric coefficient.
