Abstract
Official abstract text for this publication.
Embodiments of the invention relate to a novel class of polymers with superior mechanical properties and chemical stability, as compared to known polymers. These polymers are particularly well suited for use in anion exchange membranes (AEMs), including those employed in fuel cells. Novel methods for the manufacture of these polymers are also described.
First claim
Opening claim text (preview).
What is claimed is: 1. A polymer according to formula I wherein Ar is an aromatic compound, r is from 100 to 1,000,000, and R 2 comprises a quaternary ammonium group, and wherein the aromatic compound is selected from a group consisting of: 2. The polymer of claim 1 , wherein R 2 comprises R is an alkyl group; and n is from 1 to 20. 3. The polymer of claim 1 , prepared from a bromoalkylated precursor polymer of formula II according to the reaction: wherein R 1 is and R 2 comprises wherein n is from 1 to 20, and R is an alkyl group. 4. The polymer of claim 3 , wherein the bromoalkylated precursor polymer of formula II is prepared according to the reaction: 5. The polymer of claim 1 , wherein the polymer is used in fuel cell, water electrolysis, metal-air battery technologies, or as an antimicrobial coating. 6. A polymer according to formula: wherein x+y=1, and n is from 100 to 1,000,000.
