NEW ION-EXCHANGE COMPOSITE MEMBRANES USING STYRENE-TYPE AND ACRYLATE-TYPE MONOMERS AND PREPARATION PROCESS THEREOF

摘要

The present invention is a styrenic - relates to acrylate-based copolymer is a cation exchange compound of the containing new membrane and preparation method thereof, and more particularly, including the styrenic monomer and the (meth) acrylate-based monomer, cross-linker and initiator the polymerization solution for, after impregnating a porous film by polymerization of a series of manufacturing process for forming the introduction of sulfonic acid groups and carboxylic acid groups, a low methanol permeability and electrical resistance ionic conductivity, improved mechanical properties and processability fuel cell and electric styrene, which can be useful for composite membrane for dialysis-acrylate-based copolymer is contained in the cation exchange membrane novel compound and a process for their preparation.
