Abstract

Amphiphilic graft copolymers comprising poly(vinyl chloride) (PVC) main chains and poly(oxyethylene methacrylate) (POEM) side chains, i.e. PVC-g-POEM, were synthesized via atom transfer radical polymerization (ATRP) using direct initiation of the secondary chlorines of PVC. Successful synthesis of the graft copolymer was confirmed using 1HNMRand FT-IR spectroscopy.TEMand DSC analysis revealed the welldefined microphase-separated structure of the graft copolymer into hydrophobic PVC and hydrophilic POEM domains. All the membranes exhibited amorphous structures and the intersegmental d-spacing were increased with the grafting degree, as characterized by XRD analysis. Permeation experimental results using a CO₂/N₂ (50/50) mixture indicated that as an amount of POEM in a copolymer increased, CO₂ permeability increased dramatically without the sacrifice of selectivity. For example, the CO₂ permeability [1×10^-8 cm³(STP) cm/cm² scmHg (100 Barrer)] of PVC-g-POEM with 70 wt% of POEM at 25 °C was about 70 times higher than that of the pure PVC membrane [1.45×10^-10cm³(STP) cm/cm² scmHg (1.45 Barrer)].
