Application No. 09/909,898
5. A process for producing an anion exchange membrane, which comprises mixing a
thermoplastic polymer having no ion exchange groups with a polymerizable component
comprising a monomer of the formula (2):
wherein A is a C3-8 alkylene group or an alkyleneoxyalkyl group having a total carbon
number of from 4 to 9, and Z is chlorine, bromine, iodine, a hydroxyl group, a tosyl group,
a primary to tertiary amine, or a -NR1 R2R3 group, wherein each of R1, R2 and R3 is a hydrogen
atom, a C1-6 alkyl group of a hydroxyl group, and wherein any hydrogen atom bonded to the
benzene ring may be substituted by an alkyl group or a halogen atom, or a mixture of the
monomer of the formula (2) and a monomer copolymerizable therewith, and then polymerizing
the polymerizable component.
As evidence of unpatentability, the Examiner relies upon the following prior art
