Poly(DM-co-AN) was synthesized by the usual radical polymerization of 2-(N
N-dimethyl aminoethyl methacrylate) and acrylonitrile.The chemical structure of the poly(DM-co-AN) was analyzed by viscosity measurement
elemental analysis
infrared spectrum(FTIR) and X-ray diffraction(XRD).The effect of reaction condition on chemical structure and the effects of carrier content
gas feed pressure and temperature on permeability of the facilitated transport membrane were investigated. The results showed that the membrane displayed a CO2 permeation rate of 3.53×10-12 cm3(STP)8226;cm-28226;s-18226;Pa-1 and CO2/CH4 ideal selectivity of 104.5 at 25℃
1140 Pa of gas pressure.Both CO2 permeation rate and selectivity of CO2/CH4 decreased with increasing pressure on feed gas.The facilitated transport mechanism of CO2 in membrane was analyzed by the infrared spectra of the membranes in different states.
