The effects on PP and PS components of AlCl_3 were investigated first, mainly by rheology, including steady rheology method and dynamic rheology method. Then the in-situ reactions in PP/PS alloys under different conditions were executed and studied in detail by selective Soxhlet solvent extraction. And at the same time, the evolutions of phase structures of PP/PS and the resulted PP/PS/AlCl_3 alloys were investigated by SEM and SALS. The steady and dynamic rheological behaviors of in-situ compatibilized PP/PS alloys were obtained systematically.
