Abstract
Official abstract text for this publication.
A process for separating components of a gas mixture using gas-separation copolymer membranes. These membranes use a selective layer made from copolymers of an amorphous perfluorinated dioxolane and a fluorovinyl monomer. The resulting membranes have superior selectivity performance for gas pairs of interest while maintaining fast gas permeance compared to membranes prepared using conventional perfluoropolymers such as Teflon® AF, Hlyflon® AD, and Cytop®.
First claim
Opening claim text (preview).
We claim: 1. A process for separating two components, A and B, of a gas mixture having a ratio (Rf) of A:B, comprising: (a) passing the gas mixture across a separation membrane having a feed side and a permeate side, the separation membrane having a selective layer comprising a copolymer consisting of a perfluorinated dioxolane monomer and a fluorovinyl monomer selected from one of the following formulas: F 2 C═CFR, where R is H, C1, a C1 -C6 perfluoroalkyl, or OX. where X is a C…
