METHOD FOR PRODUCING SYNTHETIC ISOPRENE POLYMER LATEX, SYNTHETIC ISOPRENE POLYMER LATEX, COMPOSITION FOR DIP MOLDING, AND DIP MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a method for producing synthetic isoprene polymer latex, in which the amount of a synthetic isoprene polymer to be discarded in production can be reduced, and to provide a composition for dip molding, from which a dip molding having excellent tensile strength is obtained.;SOLUTION: The method for producing synthetic isoprene polymer latex comprises the steps of: mixing/emulsifying an organic solvent solution of the synthetic isoprene polymer with an aqueous solution of a surfactant to obtain an emulsified mixed solution; removing the organic solvent from the emulsified mixed solution to obtain the synthetic isoprene polymer latex; centrifuging the obtained synthetic isoprene polymer latex to obtain the synthetic isoprene polymer latex as a light liquid and an effluent, which contains the synthetic isoprene polymer and the surfactant and has the solid content concentration of 1-30 wt.%, as a heavy liquid; and removing the surfactant and water from the obtained effluent to obtain the synthetic isoprene polymer latex which has the solid content concentration of 35-70 wt.% and contains 100 pts. wt. of the synthetic isoprene polymer and 1-10 pts. wt. of the surfactant.;COPYRIGHT: (C)2016,JPO&INPIT
