Synthesis of Ionic CO_2 Copolymers

Liu Sa 1 Jia De_min 1 Chen Li_ban 2 (1. Institute of Materials Science and Engineering, South China University of Technology, Guangzhou 510640, China; 2. Guangzhou Institute of Chemistry, Academia Sinica, Guangzhou 510650, China)  
CO 2 copolymers containing anions or cations are synthesized. A kind of new CO 2 copolymer ionomer containing quaternary ammonium cationic CO 2 copolymers is obtained from chain extending reaction (using TDI as an extender) of poly (propylene carbonate) (PPC) and quaternized polyepichloro_hydrine. By changing the proportion between PPC and QPECH or molecular weight of PPC, a series samples of which quaternary ammonium cationic contents and distribution are different from each other are synthesized. Besides, by grafting copolymerization, a new branched ionomer (PMAPC_AA) containing —COOH is synthesized from terpolymer of CO 2_expoxid_maleic anhydride. The solubility of the branched copolymer depends many infactors. The preparation conditions of PMAPC_AA are optimized. The new ionomers are characterized by the FTIR, 1HNMR, ionic titration and elemental analysis (N).
