PREPARATION METHOD OF AQUEOUS DISPERSION OF SOLID RUBBER

摘要

PROBLEM TO BE SOLVED: To provide a preparation method of an aqueous dispersion of a solid rubber, which realizes a latex-like liquid of the solid rubber in the form of a dispersion by dispersing solid rubber particulates in water and enables analysis such as NMR by using the latex-like liquid of the solid rubber as a sample. SOLUTION: The preparation method comprises steps wherein (A) a swollen rubber is formed by swelling the solid rubber with a solvent, (B) the solid rubber particulates are formed by freezing and pulverizing the swollen rubber in the presence of a surfactant and (C) the particulates are dispersed in water. Preferably, the preparation method further comprises a step wherein (D) the solvent and/or the surfactant are separated and removed from the particulates. COPYRIGHT: (C)2006,JPO&NCIPI
