[0134]
[0135] The vinyl chloride resin composition of the present invention can be prepared by mixing the above-mentioned components.
[0136] Here, the mixing method of (a) vinyl chloride resin, (b) diester plasticizer, (c) trimellitate plasticizer added as needed, and additives is not limited. A preferable mixing method is a method in which components other than the plasticizer and the release agent (including the above-mentioned (y) vinyl chloride resin particles) are mixed by dry blending, and then the plasticizer and the release agent are sequentially mixed. For dry blending, it is preferable to use a Henschel mixer. In addition, the temperature at the time of dry mixing is preferably 50°C or higher and 100°C or lower, more preferably 70°C or higher and 80°C or lower.

Embodiment
[0145] Hereinafter, although an Example demonstrates this invention in detail, this invention is not limited to these Examples.
[0146] In addition, the diester plasticizer used in the Example and the comparative example was prepared as follows.
manufacture example 1
[0147] Production of 1,9-nonanediol diester plasticizer
[0148] 0.80 parts by mass (5.00 parts by mole) of 1,9-nonanediol, 1.08 parts by mass (7.52 parts by mole) of 1-octanoic acid, and 0.54 parts by mass (2.98 parts by mole) of 1-decanoic acid, relative to the total amount added 5% by mass of xylene and 0.2% by mass of p-toluenesulfonic acid relative to the total amount added to a four-necked flask with a stirrer, a thermometer, a nitrogen blowing tube and a water fractionation receiver with a condenser tube, at 160 ° C The esterification reaction is carried out until the theoretical amount of water produced is accumulated in the water fractionation receiver.
[0149] After completion of the reaction, excess acid and xylene were distilled off to obtain a crude product of esterification. Next, the obtained esterified crude product was neutralized with saturated aqueous sodium bicarbonate solution, and washed with water until it became neutral.
[0150] Then, the esterific...
