Sulfonated polyarylene ether copolymer including perfluorcyclic butane group, preparation method thereof and use thereof

摘要

The present invention is a cycle comprising a sulfonated Bhutan perfluoroalkyl copolymers, their preparation and use thereof relates to copolymers comprising a perfluoro butane cycle according to the present invention can be easily prepared in a solution or molten state , the produced electrolyte membrane having a high proton conductivity , mechanical properties and excellent chemical stability as well as to the distribution of sulfonic acid groups in the polymer backbone , location , number and so on can be controlled , because the polymer blend film further sulfonic acid groups does not entail a decrease in the physical properties due to the increase of the film , cross-linked polymer film, a polymer composite membrane , flat membrane , hollow fiber membrane , tube membrane fuel cell membrane is processed in a variety of forms , an ion exchange membrane , a dehumidifying membrane , a humidifying membrane , etc. can be useful .
