Document Type and Number:
Japanese Patent JP2002212286
Kind Code:
A
Abstract:
To provide a polymer usable as a polyelectrolyte excellent in durability.
The polymer contains at least 1.5 meq/g of an ionic group in the molecule, has a logarithmic viscosity, of a 0.05 dl/g methanesulfonic acid solution at 25°C, of at least 0.1 dl/g, and decreases in its weight by at most 5% when immersed in water at 25°C.
