Abstract
Gas separation membranes are provided and more particularly, a series of addition-type and ROMP type polynorbornenes with substituents derived from Mizoroki-Heck reactions are provided and have particular utility as gas separation membranes for natural gas upgrading.
Claims33
A process for forming a Mizoroki-Heck derived polynorbornene that is suitable for use as a gas separation membrane comprising:
- producing a substituted norbornene monomer by a Mizoroki-Heck coupling reaction in the presence of a catalyst;
- and
- polymerizing the substituted norbornene monomer to form the Mizoroki-Heck derived polynorbornene.
A gas separation membrane comprising:
- a Mizoroki-Heck derived polynorbornene.
