ABSTRACT OF THE DISCLOSURE Emulsion polymerization type thermoplastic resin of high performance can be produced by the following methods: namely, a method which comprises removing an aqueous phase from a two-phase mixture comprising a latex of polymer (1) produced by emulsion polymerization, a water soluble agent (2) in an amount of 10% by weight or less of said polymer (1) which is capable of coagulating the latex of polymer (1) and an organic agent (3) in an amount of 0.1 to 6 times the weight of said polymer (1) which is capable of dissolving both an uncrosslinked polymer contained in said polymer (1) and thermoplastic polymer (4) mentioned hereinbelow and has a solubility in water of 5% by weight or less at 25°C, then melt-mixing molten polymer which has been subjected to a first devolatiliza- tion by a thermal means with thermoplastic resin (4) and then subjecting the mixture to a second devolatilization; and a method which comprises removing an aqueous phase from a two-phase mixture comprising a latex of polymer (1) produced by emulsion polymerization, a water soluble agent (2) in an amount of 10% by weight or less of said polymer (1) which is capable of coagulating the latex of polymer (1) and an organic agent (3) in an amount of 0.1 to 6 times the weight of said polymer (1) which is capable of dissolving an uncrosslinked polymer contained in said polymer (1) and has a solubility in water of 5% by weight or less at 25°C and then melt-mixing the molten polymer from which volatile component has been devolatilized by a thermal means with thermoplastic polymer (4').
