Gas separation properties of Troeger’s base-bridged polyamides

Year: 2017

Type: article

Abstract: A series of new polyamides (PAs) has been prepared from a Troeger base-bridged diamine (TB), 2,8- diamino-4,10-dimethyl-6H,12H-5,11-methanodibenzo[1,5]-diazocine and different commercially available diacid monomers via the conventional polycondensation method. Dense membranes were prepared from the PAs by solution casting and solvent evaporation techniques. The synthesized PAs showed high glass transition temperature (283–290°C), 10% weight loss up to temperature 431°C in air, and tensile strength up to 91 MPa. The PA membranes showed higher permeability than some commercially used glassy polymers (P CO 2 up to 109 and P O 2 up to 21 Barrer) and permselectivity (P CO 2 /P CH 4 up to 53.7 and P O 2 /P N 2 up to 7.52) in comparison to many other PAs published in the literature.
