     to improve both the mechanical and thermal properties of kaolin/polypropylene (pp) composites, kaolin was modified by using 3-(trimethoxysilyl) propylmethacrylate (ydh-570) as a coupling agent to form polymerizable particle. styrene was radically polymerized through the immobilized vinyl using benzoyl peroxide (bpo) as an initiator. fourier transform-infrared (ftir) spectroscopy, particle size distribution, x-ray diffraction (xrd) and thermo-gravimetric analysis (tga) well demonstrated that the kaolin–polystyrene particles were successfully synthesized via in-situ polymerization. while the modified kaolin and raw kaolin were introduced into the pp matrix, it could be concluded that modified kaolin/pp composites have better mechanical and thermal properties than raw kaolin/pp composites, and these improvements were attributed to the desirable dispersion of kaolin in pp matrix.
