Abstract :
New semi-interpenetrating polymer networks (semi-IPNs) were prepared on the basis of linear polyurethane (LPU) and trimerized dicyanic ether of bisphenol-A crosslinked (TDCE). Their structural properties were investigated by wide-angle and small-angle X-ray spectroscopy (WAXS and SAXS). The dynamic dielectric properties were measured by thermally stimulated depolarization currents (TSDC) techniques and broadband dielectric relaxation spectroscopy (DRS). All techniques provide strong evidence for homogeneous structure without any indication of microphase separation
