Abstract
To elucidate the interfacial interaction between the encapsulating polymer and the inorganic powders, the molecular aggregation of the encapsulating polymer was clarified by the experimental results of the thermal behavior, density, infrared spectrum, and molecular weight distribution. Comparison of the thermal properties of TiO2 encapsulating poly- (methyl methacrylate) and polystyrene with those of the TiO2 dispersion polymer showed that the encapsulating polymer has two thermal relaxation regions. In addition, the experimental results of GPC, density, and infrared spectrum indicated that the encapsulating polymer has a molecular structure with high density, high molecular weight, and more tacticity.
