An object of the present invention is to provide a high-performance polymer dispersant that can be applied to cellulose being a hydrophilic substance, and another object of the present invention is to provide a technology for practical application of obtaining a cellulose-dispersed resin composition that realizes stable dispersion of cellulose in a simpler manner and in an environmentally conscious manner that never uses a large amount of organic solvents when the polymer dispersant for cellulose is applied to cellulose and disperses the cellulose in a thermoplastic resin. These objects are achieved by providing a polymer dispersant for cellulose, being a polymer compound including a block copolymer structure having a resin-affinitive segment A and a cellulose-adsorptive segment B, the polymer compound synthesized by a reversible chain transfer catalyzed polymerization (RTCP) method not using any of a heavy metal, a nitroxide compound, and a sulfur-based compound, using an organic iodine compound as an initiation compound, and using a phosphorus compound, a nitrogen compound, an oxygen compound, or a carbon compound as a catalyst.

A preparation method for an emulsifier, an emulsifier, an aqueous epoxy resin dispersion, and a formulation method. The preparation method for an emulsifier comprises reacting aminosulfonic acid and/or a sulfamate as a first reaction raw material with an epoxy resin in the presence of water, so as to obtain an ionic active emulsifier. The ionic active emulsifier molecule comprises at least one epoxy group from an epoxy resin and at least one sulfonic acid or sulfonate group from the first reaction raw material. The aqueous epoxy resin dispersion prepared by using the emulsifier has the characteristics of good stability and good corrosion resistance after curing, and can be used in the fields of coatings, adhesives, etc.

A suspension of a water soluble anionic polymer suspended as a solid in a nonaqueous carrier fluid includes at least about 20 wt % water soluble anionic polymer and less than about 5 wt % water. The water soluble anionic polymer may be an acrylate or methacrylate based homopolymer or copolymer polymerized with an acrylamide- or styrene-based monomer. The water soluble anionic polymer may be a naturally occurring biopolymer or derivative thereof such as lignosulfonate. Mixtures of more than one polymer may be used. The nonaqueous carrier fluid may comprise or consist essentially of mineral oil and/or an alcohol, ether or acetate derivative based on ethylene glycol and/or propylene glycol. The suspension can be used for treating mineral slurries such as those generated in mining operations and generally for dispersing particles in aqueous solution.
