Abstract: In view of lacking affinity between PP and mica the property improving of PP by mica is not definite. The superfine mica was treated with coupling agent KH-570 and the PP/mica was compatibilized by PP-g-MAH. Results showed that, strength, modulus, hardness and toughness of PP were raised efficiently and simultaneously. As a result of increasing the interfacial strength and the interfacial layer thickness by PP-g-MAH, the mechanical properties of PP/PP-g-MAH/mica were better than that of PP/mica when the mica was disposed with KH-570. Furthermore, the mica possessed obvious nucleation effect on the crystallization process of PP, thus the crystallization temperature and the melting temperature of the modified PP were increased.
