A novel phenolic rigid organic filler (named K3) was dispersed in isotactic polypropylene matrix (iPP) by melt-mixing processes, and a series of K3/iPP blends were prepared with or without maleic anhydride-grafted polypropylene (MAPP) as compatibilizer. The influences of K3 and MAPP on the filler dispersion were studied using Polaried Optical Microscope (POM) and Fourier Transform Infrared Spectroscopy (FTIR), and the influences on the modulus of blends were studied by tensile test and dynamic Mechanical Analysis (DMA). It was found that K3 can be dispersion in iPP matrix at spherical form and its particles size can be increased with K3 content increased. The incorporation of K3 can obviously improve the Young’s modulus and storage modulus of blends.
