Propene/1-alkene copolymers as a novel membrane material for O2/N2 separation

Propene/1-alkene copolymers were synthesized by means of slurry polymerization process under atmospheric pressure using Ziegler–Natta catalysts. Experimental results demonstrated that they were random, low-crystalline, and elastic. Moreover, they were tested to show high O2 or N2 permeance and relatively high O2/N2 selectivity.
