| Abstract: | A Study has been made on the DSC, WAXD, TMA, TG and mechanical tests of polypropylene filled with rare-earth oxides, viz., La2O3 Nd2O3 and Y2O3. It was found that the crystallization temperature of the composite increases with increasing the content of the rare-earth oxide, but the melting temperature remains almost invariant.The relative proportions of p-form in the specimens were measured with WAXD by an empirical ratio K.The K value obtained increases with increasing content of the rare-earth oxides.The tensile strength of the composite decreases as the amount of rare-earth oxides increases, while the impact strength keeps nearly constant. |
