According to the advantages and disadvantages of PP and PET, and carry on the modification, will both for blending. But PP and PET belong to thermodynamics incompatible system, direct blend of words, blending system interface force is small, poor compatibility, the serious influence by blending with the mechanical properties of materials. Therefore, this paper studies using PP-g-GMA improve PP/PET composite material compatibility. Then through the tensile, melting and the isothermal crystallization tests found that both can mutual optimize their performance: PET can improve the strength of the PP, modulus, heat resistance, it can improve the crystallization of PP ability; And PP is able to reduce the PET processing temperature, increase mechanical properties, etc.
