摘要

The object of the present invention is to provide a manufacturing method of an emulsifier and a manufacturing method of an emulsifier for producing a material which can suppress the reduction of emulsion and dispersion function of the particle diameter of the hydrophilic nanoparticles. A dispersion step of preparing a dispersion by dispersing in water, the granules comprising a conjugate of a polycondensation polymer particles having a hydroxyl group, a manufacturing method of an emulsifier for producing materials, the hydrogen bond to swell the granules derived from the granules more By cutting with reversible conditions, has a palliative generating step of generating a palliative that conformation of the binding body is relaxed. Production method of the emulsifier has a particle separation step by using the emulsifier for the production material, cut the hydrogen bond of the coupling body, to separate the water polycondensation polymer particles.
