ABSTRACT:
A conjugated diene sulfonation product represented by the formula (I): ##STR1## wherein R.sup.1 to R.sup.6, which may be the same or different, represent hydrogen atoms, alkyl groups having 1 to 8 carbon atoms, aryl groups having 6 to 20 carbon atoms or --SO.sub.3 X groups (X represents a hydrogen atom, a metal atom, an ammonium group or a quaternary ammonium group), at least one of said R.sup.1 to R.sup.6 being the --SO.sub.3 X group, a polymer of the conjugated diene sulfonation product or a copolymer of the conjugated diene sulfonation product with a monomer copolymerizable therewith. The sulfonation product, the polymer and the copolymer are useful as a dispersing agent for preparing a solid fuel dispersion, a cement dispersion, a dye and/or pigment dispersion or a metal oxide dispersion or as a water-treating agent, a fiber-treating agent, a plating bath additive and an excavation-muddy water-viscosity-adjusting agent.
