preparation example 1
[0190] (preparation of rubber-containing multistage polymer (I))
[0191] Put 10.8 parts of deionized water in a container with a mixer, add 0.3 parts of MMA, 4.5 parts of n-BA, 0.2 parts of 1,3-BD, 0.05 parts of AMA and 0.025 parts of CHP, and stir and mix at room temperature . Next, while stirring, 1.3 parts of an emulsifier (manufactured by Toho Chemical Industry Co., Ltd., trade name "Phosphamol RS610NA") was added to the container, and stirring was continued for 20 minutes to prepare an emulsion. Then, 139.2 parts of deionized water were charged into a polymerization vessel equipped with a cooler, and the temperature was raised to 75°C. Furthermore, 0.2 parts of sodium formaldehyde sulfoxylate, 0.0001 parts of ferrous sulfate, and 0.0003 parts of EDTA were added to 5 parts of ion-exchanged water, and the resulting mixture was added to the polymerization vessel at one time. Next, 8 minutes passed while stirring under a nitrogen atmosphere, and the mixed emulsion was drop...

[0194] (Preparation of rubber-containing polymer (I'))
[0195] Under a nitrogen atmosphere, 244 parts of deionized water was added to a reaction vessel with a reflux cooler, and the temperature was raised to 80°C. Next, add (1) shown in Table 1, and while stirring, add 1 / 15 of the raw material (2) for the first-stage polymer (I'-A-1) of the elastomer polymer shown in Table 2. ), and keep for 15 minutes. Next, the remaining raw material (2) was continuously added at a rate of 8% / hour with respect to the increase rate of the water monomer component [raw material (2)], and then kept for 60 minutes to obtain the first-stage polymerization of the elastomeric polymer. Object (I'-A-1) latex. The Tg of the polymer (I'-A-1) itself was 24°C. Next, 0.6 parts of sodium formaldehyde sulfoxylate was added to the obtained latex, and kept for 15 minutes. Then, under a nitrogen atmosphere, while stirring at 80° C., the second amount of the elastomer polymer shown in Table 2 was continuous...

[0201] (Preparation of thermoplastic polymer (IV))
[0202]200 parts of ion-exchanged water replaced with nitrogen was added to the reaction vessel, furthermore, 1 part of Kao Co., Ltd. product named "LATEMUL ASK" was added as an emulsifier and 0.15 parts of potassium persulfate. Next, 40 parts of MMA, 2 parts of n-BA, and 0.004 parts of n-OM were added, stirred at 65° C. for 3 hours in a nitrogen atmosphere, and the polymerization was completed. Then, a monomer component consisting of 44 parts of MMA and 14 parts of n-BA was added dropwise over 2 hours, and then held for 2 hours to complete polymerization. Add the obtained polymer latex of the thermoplastic polymer (IV) to 0.25% sulfuric acid aqueous solution, and after the polymer is acid-precipitated, dehydrate, wash with water, and dry to recover the powdery thermoplastic polymer (IV). The reduced viscosity of the obtained thermoplastic polymer (IV) was 0.38 L / g.
