Title: HIGHLY SELECTIVE POLYNORBORNENE HOMOPOLYMER MEMBRANES FOR NATURAL GAS UPGRADING
Abstract:
Embodiments for a crosslinked alkoxysilyl polynorbornene homopolymer and methods of making crosslinked alkoxysilyl polynorbornene homopolymer are provided, where the method comprises polymerizing through addition polymerization or ring opening metathesis polymerization a norbornene monomer comprising an alkoxysilyl moiety in the presence of a catalyst to produce an alkoxysilyl modified polynorbornene homopolymer, and producing a crosslinked alkoxysilyl polynorbornene homopolymer through sol-gel initiated crosslinking of the alkoxysilyl modified polynorbornene homopolymer at ambient conditions, or acid-catalyzed conditions.
