MONOMER BEADS FOR PRODUCING A PROTON-CONDUCTING MEMBRANE

Monomer beads which can be obtained according to a process in which i. one or more aromatic tetraamino compounds are mixed with one or more aromatic carboxylic acids comprising at least two acid groups per carboxylic acid monomer in an extruder and melted at 190° C.-270° C.; ii. the melt is dropleti...

More Information
Summary:Monomer beads which can be obtained according to a process in which i. one or more aromatic tetraamino compounds are mixed with one or more aromatic carboxylic acids comprising at least two acid groups per carboxylic acid monomer in an extruder and melted at 190° C.-270° C.; ii. the melt is dropletized at 190° C.-270° C. by means of a die located at the extruder outlet; iii. the liquid droplets are collected, cooled and allowed to solidify. The monomer beads are particularly suited to the production of a proton-conducting polymer membrane based on polyazoles.
