Cage silsesquioxane, denoted as polyhedral oligomeric silsesquioxane (POSS) has high crystallinity to readily cause aggregation when it is induced into polymer side chain. In this work, side‐opened POSS was employed to construct a bifunctional monomer for cyclopolymerization. The collapsed symmetry of the POSS core effectively reduced the crystallinity to realize homogeneous films, while a traditional POSS homopolymer formed turbid and brittle films. The obtained film showed high transparency and thermal stability.

可溶且可成膜的均聚物束缚侧开笼式倍半硅氧烷悬垂物

笼型倍半硅氧烷，表示为多面体低聚倍半硅氧烷（POSS），具有高结晶度，当被诱导成聚合物侧链时容易引起聚集。在这项工作中，采用侧开式POSS来构建用于环聚合的双功能单体。POSS核的坍塌对称性有效地降低了结晶度，从而实现了均质膜，而传统的POSS均聚物则形成了浑浊和脆性的膜。所得膜显示出高透明性和热稳定性。
