Relaxation processes in polyethylene fibre-reinforced polyethylene composites

Distributed Physical and Molecular Separations for Selective Harvest of Higher Value Wheat Straw Components Project

“…For composites, high activation energies are associated with large degrees of interactions between polymer matrix and filler. In general, activation energies obtained for the α-transition in our SPC are comparable to literature values for various polyethylenes and polyethylene-based composites (Matsuo et al 2003, Vaisman et al 2003, Pegoretti et al 2000.…”

Amorphous and crystalline phase interaction during the Brill transition in nylon 66

“…An appropriate example from our own research is of high density polyethylene (HDPE), which in its pristine form exhibits a single second order transition, namely, T g . However, after undergoing a certain solid state crystallization stage, which results in crystalline restructuring, the same HDPE exhibits an untypically immense β transition in the amorphous phase [4,5]. In the present study we deal with yet another first order transition, namely the Brill transition in polyamides (e.g., nylon 66), for which a counterpart transition in the amorphous phase is explored.…”
