Title: Accessing siloxane functionalized polynorbornenes via vinyl-addition polymerization for CO 2 separation membranes

Abstract

Here, the vinyl addition polymerization of norbornylbased monomers bearing polar functional groups is often problematic, leading to low molecular weight polymers in poor yield. Herein, we provide proof-of-principle evidence that addition-type homopolymers of siloxane substituted norbornyl-based monomers may be readily synthesized using the catalyst trans-[Ni(C 6F 5) 2(SbPh 3) 2]. Polymerizations using this catalyst reached moderate to high conversion in just 5 min of polymerization and produced siloxanesubstituted polymers with molecular weights exceeding 100 kg/mol. These polymers showed excellent thermal stability (T d ≥ 362 °C) and were cast into membranes that displayed high CO 2 permeability and enhanced CO 2/N 2 selectivity as compared to related materials.
