| Abstract: | From relaxation investigations on the electric charge of the electrically polarized polymer, physical aspects of the effect of tri-basic lead sulphate, as a stabilizer, on the dielectric relaxation properties of PVC are considered. The results correlate with the established fact that tri-basic lead sulphate as a dispersion additive has a marked influence on the process of structure formation, changing the dielectric relaxation properties of the polymer. |
