Abstract:A new strategy was developed to build a CO2-philic/hydrophilic surfactant by combining the common free radical polymerization and the grafting modification technology, and a brush polymer was synthesized with poly(vinyl acetate)-based copolymer as the CO2-philic group (as the main chain) and the methoxy polyethylene glycols (MPEG) as the hydrophilic part (as the branched chain) (PVAc-g-MPEG). The CO2-philic ability can be controlled by adjusting the chain length of the PVAc fragment. The results indicate that … Show more
