Title:
POLYSTYRENE SULFONATE COPOLYMER, DISPERSANT USING SAME, AQUEOUS NANOCARBON MATERIAL DISPERSION, AND METHOD FOR PRODUCING POLYSTYRENE SULFONATE COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2013/042482
Kind Code:
A1
Abstract:
Provided is a novel polystyrene sulfonate copolymer which is useful as a dispersant for producing an aqueous dispersion of a nanocarbon material such as a carbon nanotube, a graphene or a fullerene.
A polystyrene sulfonate copolymer which is composed of a styrene sulfonate monomer residue, an N-substituted maleimide monomer residue, and if necessary a residue of another vinyl monomer that is copolymerizable with the styrene sulfonate monomer and the N-substituted maleimide monomer; a dispersant which contains the polystyrene sulfonate copolymer as an active ingredient; an aqueous dispersion of a nanocarbon material, which uses the dispersant; and a method for producing the polystyrene sulfonate copolymer.
