Abstract

3-[Tris-(trimethylsiloxy)silyl] propyl acrylate (TRIS-A) was copolymerized with poly(ethylene glycol) diacrylate (PEGDA), and the gas transport and physical properties of the resulting copolymers were characterized. Introduction of TRIS-A led to increased polymer fractional free volume and strong broadening of the glass-rubber relaxation without a significant shift in glass transition temperature in samples containing up to 80wt% TRIS-A. Gas permeability increased significantly as TRIS-A content increased: for instance, addition of 80wt% TRIS-A increased CO₂ permeability from 110 to 800barrer. The strongly non-polar character of TRIS-A, however, resulted in progressively lower CO₂ affinity for the polymer network, leading to decreased CO₂/light gas selectivity with increasing TRIS-A content.
