Abstract
A polymeric composite may be used for forming fluid separation membranes. The fluid separation membranes may go through a separation selectivity maximum as a function of operating conditions (e.g., temperature and/or pressure). The membranes may be formed from polyamide or poly (pyrrolone-imide). Polyamides may be formed by the condensation of a tetraamine, a tetraacid, and a diamine. Poly (pyrrolone-imides) may be formed by the condensation of a polyamide.
