Porous Polymers Derived from Octavinylsilsesquioxane by Cationic Polymerization

Front Cover: In article number 1800536 by Hongzhi Liu and co-workers, a new rapid and efficient approach is developed for the preparation of porous materials via the cationic polymerization of octavinylsilsesquioxane. A series of experiments are conducted to clarify the effects of reaction time, temperature, and solvent on the polymerization process. The porosity of these polymers can be readily tailored by changing reaction conditions.
