TL;DR: In this paper, the authors used the Flory-Huggins interaction parameter χ to estimate the crosslink density from the equilibrium volume fraction of rubber in the swollen state, and established a relationship between χ and vr, the polymer volume fraction at equilibrium (maximum) degree of swelling.

TL;DR: In this article, the authors reported an easy technique to produce cured styrene butadiene rubber (SBR)/multi-walled carbon nanotubes (MWCNT) composites with a sulphur/accelerator system at 150°C.

TL;DR: In this paper, the authors investigated the dependence of the physical properties of styrene-butadiene rubber copolymers (cured with different sulphur content, in order to obtain various networks) on the crosslink density by means of dynamical mechanical analysis, differential scanning calorimetry and positron annihilation lifetime spectroscopy.

TL;DR: In this article, the authors evaluated the crosslink densities of polybutadiene rubber in the presence of sulphur and accelerator in their composition and were vulcanized at 433 K at different times in order to obtain several network structures.

TL;DR: This paper addresses the problem of dielectric breakdown in composite materials with a generalized model that propagates according to new rules to take into account electrical properties and particle size.
