Synthesis of Hypercrosslinked Adsorbent Resin Based on the Copolymer of Styrene-Bis( p-vinylphenyl) Ethane and its Adsorption Property for Theophylline
In order to overcome the defects of structural heterogeinity and severe tailing in adsorption-desorption of commercial hypercrosslinked adsorbent resins,novel hypercrosslinked adsorbent resin with homogeneous structure was synthesized via Friedel-Crafts postcrosslinking of styrene-bis( p-vinylphenyl) ethane copolymers. By measuring the residual content of chlorine,specific surface area,pore volume,pore size and infrared spectrum,the structure of the resin could be analyzed. Furthermore,adsorption behaviors ...
