摘　　要：以无定形二氧化硅(SiO2)为基本原料,经过系列反应成功合成了带有甲基丙烯酸酯基团的笼形倍半硅氧烷。采用红外光谱、差示扫描量热等分析方法对各步反应产物进行了表征。结果表明,所合成的倍半硅氧烷带有可聚合的不饱和基团且具有笼形核/壳结构。可聚合的笼形倍半硅氧烷为具有特殊杂化结构聚合物的合成和应用奠定了基础。Polymerizable polyhedral oligomeric silsesquioxane with methacrylic group was successfully synthe- sized through series reaction with silicon dioxide（SiO2 ） as starting material. The reaction products from each reaction were characterized by FT-IR, DSC. The results showed that methacrylic group has covalently linked to the synthe- sized cubic core/shell structure of polyhedral oligomeric silsesquioxane. The polymerizable polyhedral oligomeric sil- sesquioxane would lay the foundation for synthesis and application of polymer with hybrid structure.
