介绍。有机-无机杂化材料引起了广泛关注，因为它们提供了开发高性能材料的机会，这些材料结合了传统有机和无机成分的许多理想特性，如热稳定性、溶解度和可加工性。特别是，多面体低聚倍半硅氧烷（POSS）是一类令人感兴趣的无机组分。它具有纳米级二氧化硅笼状结构，可以用多种有机基团进行功能化。 1 使用 POSS 衍生物作为单体已被证明是纳米复合材料设计 2 以及杂化聚合物中侧链 3 或端基 4 的有效方法。将 POSS 掺入一些聚合物中可以提高物理性能，例如热稳定性和机械稳定性、3c、h、l、m 可燃性、3e 抗氧化性、3i 和低介电常数。 3a，b虽然已经制备了许多基于POSS的材料，但很少有论文报道主链具有POSS的可溶性聚合物的合成。 5 在分步聚合体系中，单体必须具有精确的两个官能团才能获得线性高分子量
Introduction. Organic-inorganic hybrid materials have attracted much attention because they offer the opportunity to develop high-performance materials that combine many desirable properties of conventional organic and inorganic components such as thermal stability, solubility, and processability. Particularly, polyhedral oligomeric silsesquioxane (POSS) is an interesting class of inorganic component. It has a nanometersized silica-like cage structure and can be functionalized with a wide variety of organic groups. 1 Use of POSS derivatives as a monomer has demonstrated to be an efficient method for nanocomposite materials design2 as well as for side chains3 or end groups4 in hybrid polymers. The incorporation of POSS into some polymers have led to enhancement in the physical properties such as thermal and mechanical stability, 3c, h, l, m flammability, 3e oxidative resistance, 3i and low dielectric constant. 3a, bAlthough numerous POSS-based materials have been prepared, few papers have reported the synthesis of soluble polymers with POSS in the main chain. 5 In step polymerization system, it is necessary for the monomer to have precisely two functional groups to obtain linear high molecular weight
