Abstract
Abstract
The present invention relates to: a polyamide-based macromolecular compound which is produced by using DOCDA and one or more diamines selected from the group consisting of MDA, ODA, PDA, TDA, TrMPD, TeMPD and MBCA; and a gas-separation asymmetrical hollow-fibre membrane comprising same. The polyamide-based macromolecular compound according to the present invention can advantageously be used in the production of a gas-separation hollow-fibre membrane having an asymmetrical structure since said compound is highly viscous due to a high molecular weight in addition to having outstanding gas permeability and high selectivity while having excellent high heat resistance, chemical resistance and mechanical properties and being outstandingly soluble in polar organic solvents.
