两种无机核，由二氧化硅和二氧化钛，已通过基本Stoeber合成制备。这些核心已被官能化，使用三甲氧基甲硅烷基丙基甲基丙烯酸酯（MPTMS），并引入到细乳液共聚体系。细乳液由苯乙烯（S）和甲基丙烯酸羟乙酯（HEMA）、苯乙烯磺酸（SSA）或甲基丙烯酸氨乙酯盐酸盐（AEMA）作为共聚单体以不同的组成组成组成。通过SEM和动态光散射（DLS）测量研究了产物的形貌。通过光声红外光谱（PA-FTIR）和元素分析研究了产物的组成。通过TGA和DSC分析确定了热性能。
Two inorganic cores, consisting of silica and titania, have been prepared via basic Stoeber synthesis. Those cores have been functionalized, using trimethoxysilyl propylmethacrylate (MPTMS) and introduced into a miniemulsion copolymerization system. The miniemulsion consisted of styrene (S) and 2-hydroxyethyl methacrylate (HEMA), styrene sulfonic acid (SSA) or aminoethyl methacrylate hydrochloride (AEMA) as comonomer in varying compositions. The morphology of the products has been investigated by SEM and dynamic light scattering (DLS) measurements. The composition of the products has been investigated by photoacoustic FTIR (PA-FTIR) spectroscopy and elemental analysis. Thermal properties have been determined by TGA and DSC analysis.
