Preparation of Microporous Organic Polymers via UV-Initiated Radical Copolymerization

UV-initiated radical copolymerization has been successfully applied for the preparation of two kinds of microporous organic polymers (MOPs) based on divinylbenzene (DVB)/bismaleimide (BMI) monomers and DVB/pentaerythritol tetraacrylate (PET4A). The obtained MOPs exhibit high BET surface areas and good CO2 storage performance. The maximum BET surface areas of DVB/BMI and DVB/PET4A are 585 and 887 m2 g–1, respectively. Furthermore, the ester groups embedded on the DVB/PET4A copolymer skeleton can be easily converted into carboxylic groups by hydrolysis and show superior adsorption capacity of 485 mg g–1 toward methylene blue dye. The adoption of this highly efficient polymerization strategy offers the possibility for the economical and continuous preparation of MOPs and demonstrates great potential for industrial application.
