Title:
ベースポリマーにグラフト化されたトリフルオロスチレン含有化合物
Document Type and Number:
Japanese Patent JP2007507560
Kind Code:
A
Abstract:
A fluorinated ion exchange polymer is prepared by grafting a monomer onto a base polymer, wherein the grafting monomer is selected from the group consisting of structure 1a, 1b and mixture thereof; wherein Y is selected from the group consisting of -RFSO2F, -RFSO3M, -RSO2NH2 and -RFSO2N(M)SO2R2F, where in M is hydrogen, an alkali cation or ammonium; and RF and R2F are perfluorinated or partially fluorinated, and may optionally include ether oxygens; and n is between 1 and 2 for 1a, or n is between 1 and 3 for 1b. These ion exchange polymers are useful is preparing catalyst coated membranes and membrane electrode assemblies for fuel cells.
