Epub 2016 Dec 14.The polymer α relaxation process for net-PEA gels swollen with nonpolar p-xylene is studied by employing dielectric relaxation spectroscopy. The results present the in situ monitoring of the dielectric behavior of α relaxation process under p-xylene cold crystallization, isothermal crystallization as well as crystallization from quenching. For the partially crystallized systems, the results exhibit that the amount of p-xylene crystal phase has no remarkable effects on the time scale, being controlled mainly by the amount of the noncrystallized p-xylene (cpx= 0.
