Poly(glycidyl methacrylate-co-acrylonitrile)[poly(GMA-co-AN)] was converted to a poly[(2-oxo-1,3 dioxolane-4-yl) methyl methacrylate-co-acrlyonitrile][poly(DOMA-co-AN)] by the polymer reaction with carbon dioxide using quaternary ammonium salt as a catalyst. Qaternary ammonium salts of lager alkyl group and more nucleophilic counter anions exhibited better catalytic activity in the addition of CO2 to poly(GMA-co-AN). Poly(DOMA-co-AN) formed clear films when blended with polyetherimide (PEI). DSC analysis also showed that poly(DOMA-co-AN) containing blends were miscible in the whole composition ranges. The glass transition temperature (Tg) of the polymer blends closely matched the Fox equation.
