以苯乙烯单体和二乙烯基苯为单体，采用原位聚合法制备了聚苯乙烯凝胶和硅胶的均相互穿网络聚合物杂化物。将单体混合在四甲氧基硅烷的溶胶-凝胶反应混合物中并进行自由基聚合，得到透明的玻璃状材料。通过氮气孔隙率测定法证实了均匀性。发现有机部分以纳米尺度分散。所得IPN聚合物杂化物具有高度耐溶剂性。
Homogeneous IPN polymer hybrids of polystyrene gel and silica gel were prepared by applying an in-situ polymerization method to styrene monomer and divinylbenzene. The monomers were mixed in the sol–gel reaction mixture of tetramethoxysilane and subjected to radical polymerization, resulting in transparent glassy materials. The homogeneity was confirmed by nitrogen porosimetry methods. The organic part was found to be dispersed at the nanometer scale. The obtained IPN polymer hybrids are highly solvent resistant.
