Compatibilizing Effect of MCM-41 and PP-g-MAH on the Mechanical and Thermal Analyzer of PP/PS Blends

In order to improve compatibility between PP/PS blends, different types of fillers were prepared by melt compounding techniques. The effects of the MCM-41 and PP-g-MAH on the mechanical and crystallization properties of PP/PS composites were investigated. The results of mechanical tests showed that the co-incorporation of MCM-41 filler and PP-g-MAH gave rise to much better tensile and impact strength than adding of MCM-41 and PP-g-MAH respectively due to different interfacial structure between the fillers and the matrix. DMA attested that the good adhesion between PP/PS blend was obtained by adding MCM-41 and PP-g-MAH fillers.
