Abstract: One method as described herein relates to making a high molecular weight, monoesterified polyimide polymer using a small amount of bulky diamine.

This small amount of bulky diamines reduces chain mobility or segmental motion during crosslinking and reduces large loss of permeance. As such, this method provides a crosslinked membrane with good permeance and selectivity.
