Abstract: | This study is related to the investigation of the chemical fixation of carbon dioxide to copolymers bearing a cyclic carbonate
group and their application to polymer blends. In the synthesis of (2-oxo-l,3-dioxolan4-yl) methyl vinyl ether (OVE) from
glycidyl vinyl ether (GVE) and CO2, quaternary ammonium salt catalysts showed good yield of OVE. The results with long alkyl chain and with lower accessibility
showed a higher catalytic activity. Mixed catalyst of PEG-4000 and Nal showed higher catalytic activity than Nal alone. The
copolymer of OVE and acrylonitrile (AN) was prepared by radical copolymerization in acetonitrile at 60 °C. The monomer reactivity
ratios were given as r1(OVE)=0.36 and r2(AN)=1.21 in the copolymerization of OVE and AN. The films of poly(OVE-co-AN)/PVC blends were cast from DMF. The poly(OVE-co-AN)/PVC
blends showed good miscibility over whole composition ranges. |
