Abstract

PURPOSE: Emulsion polymerization is effected using a specific surfactant, the polymer is coagulated with inorganic salts or the like to separte from the aqueous phase, rinsed with water, the aqueous phase is treated with a semipermeable membrane and reused, thus economically producing the titled polymer with less surfactant remaining.
CONSTITUTION: Emulsion polymerization is conducted in a polymerization tank 1 using a surfactant with at least 50wt% distribution ratio to the aqueous phase between the polymer phase and the aqueous phase in latex. The latex is coagulated in a coagulation tank 2 using a coagulant composed of inorganic salts and/or inorganic acids and separated into the polymer and the aqueous phase using a sieve 3 for separating polymers. The polymer is rinsed with water 4. Further, the aqueous solution 10 that has been used in separation and rinsing and contains the surfactant and the coagulant is treated with a semipermeable membrane I with less than 90% and 60% exclusion rate to the surfactant and the coagulant respectively to separate into a surfactant solution 20 and a coagulant solution 30. Each of them is circulated for reuse.
