研究了聚甲基丙烯酸甲酯（PMMA）和聚醋酸乙烯酯（PVA）共混物的热刺激放电电流（TSDC）。极化温度和电场对共混物TSDC峰的影响表明，共混物中的极化是由于载流子在深陷阱中的俘获导致诱导偶极子的形成。A.C.的结果介质桥的测量也与TSDC的结果进行了比较。还报道了介电弛豫参数。
Thermally stimulated discharge current (TSDC) studies have been carried out on blends of polymethyl methacrylate (PMMA) and polyvinyl acetate (PVA). The effects of polarization temperature and field on the TSDC peaks of polyblends indicate that the polarization in the polyblends is due to charge-carrier trapping in deep traps which leads to induced dipole formation. The results of a.c. dielectric bridge measurements are also compared with the TSDC results. The dielectric relaxation parameters are also reported.
