The effect of polarization cooling in polypropylene has been studied. It is found that the polarization increases during quenching process. Further analysis by use of cyclic polarization TSC method where polarizing temperature changes from T p to T 0 then returns to T p shows that when T p is lower than the peak temperature, peak value increases and when T p is higher, the upper side of the peak extends. The polarization cooling strengthens the ability of polymer chains to bound the polarized charges.
