Modified polypropylene was made of melt blending using thermostable-filler and polypropylene polymers. Modified PP were characterized for the purpose of improving a thermal-property of PP polymer with the composition of 5wt %, 10wt % of thermostable-filler. The structure and thermal-property were determined from IR, DSC, TGA, and SEM instruments. From the results of this study, it found the following facts. Firstly, it was found that the modified PP was mixed with PP and thermostable-filler qualitativly. Secondaty, thermal property of modified PP was improved steadily according to increase of ratio of thermostable-filler.
