Direct polymerization of CO2 and diols is promising as a simple and environmental-benign method in place of conventional processes using high-cost and/or hazardous reagents such as phosgene, carbon monoxide and epoxides, however, there are no reports on the direct method due to the inertness of CO2 and severe equilibrium limitation of the reaction.

• Novel gas separation with temperature and pressure differences across the membrane. • Molecular exchange flow by the thermal transpiration in the porous membrane. • Low cost membrane is available for gas separation. • 15% gain of mole percentage by a membrane of 3 ×3 cm size with 45 K temperature difference. g r a p h i c a l a b s t r a c t a b s t r a c(More)
