摘要

笼型硅氧烷（POSS，多面体低聚硅氧烷）是发展有机-无机杂化聚合物的重要组成部分。然而，由于POSS的高结晶度，在其侧链中含有POSS单元的聚合物通常表现出较差的成膜性能。本研究合成了密集接枝POSS单元的聚亚甲基。这种poss -聚乙烯结构产生了均匀透明的铸膜，与poss -聚丙烯酸酯形成的浑浊膜形成对比。薄膜质量的显著差异归因于POSS结晶的抑制，这是由于POSS在聚乙烯主链上的密集系结促进的

Polymethylene with cage silsesquioxane: densely grafted structure prevents side-chain crystallization†

Cage silsesquioxane (POSS, polyhedral oligomeric silsesquioxane) is a crucial building block in the development of organic–inorganic hybrid polymers. However, polymers incorporating POSS units in their side chains often exhibit poor film-forming properties because of the high crystallinity of POSS. In this study, polymethylene densely grafted with POSS units was synthesized. This POSS-polymethylene structure produced a homogeneous, transparent cast film, in contrast to the turbid film formed by POSS-polyacrylate. The significant difference in the film quality was attributed to the inhibition of POSS crystallization, facilitated by the dense tethering of POSS on the polymethylene backbone.
