class of inorganic polymeric materials featuring a main chain consisting of PV-O bonds and aryl side groups, which was obtained with >70 repeat units by ring-opening polymerization of cyclic phosphonates. This monomer-polymer system was found to be dynamic in solution enabling selective depolymerization under dilute conditions, which can be tuned by varying the substituents. The polymers show high
我们描述了一类新的无机聚合物材料,其主链由 PV-O 键和芳基侧基组成,通过环状膦酸酯的开环聚合获得 >70 个重复单元。发现这种单体-聚合物系统在溶液中是动态的,能够在稀释条件下进行选择性解聚,这可以通过改变取代基进行调节。该聚合物对重量损失表现出高热稳定性,并且可以很容易地制成自立薄膜。还描述了环状 6 和 12 元环前体的结构特征。
