摘要
There are provided a composite particle comprising polystyrene and a filler, and having high levels of affinity between the filler and the polystyrene matrix, few or a small number of voids at the interface between the filler and the polystyrene matrix, and an excellent mechanical properties, and a method for preparing the same composite particle. The polystyrene-maleic anhydride/magnesium hydroxide composite particle is produced by bulk polymerization of a blend of a styrene monomer, a crosslinking agent, a polymerization initiator, maleic anhydride, and magnesium hydroxide which is coated with a surface-treatment agent in advance to impart hydrophobicity thereto, and subsequently suspension polymerization of a product obtained from the bulk polymerization.
