(Measurement Example 1) Measurement of Melt Viscosity of Polyphenylene Sulfide Resin
[0081]The melt viscosity of the polyphenylene sulfide resin produced in Reference Example was measured after holding the resin at 300° C., a load of 1.96×106 Pa, and L / D=10 (mm) / 1 (mm) for 6 minutes, using a flow tester, CFT-500D, manufactured by Shimadzu Corporation.
Example
(Preparation Example 1) Preparation of Polyphenylene Sulfide Resin (A-1)
[Step 1]
[0082]To a 150-L autoclave equipped with a stirring blade and connected to a pressure gauge, a thermometer, a condenser, a decanter, and a rectifying column, 33.222 kg (226 moles) of p-dichlorobenzene (hereinafter abbreviated to “p-DCB”), 3.420 kg (34.5 moles) of NMP, 27.300 kg (230 moles on a NaSH basis) of a 47.23 mass % aqueous NaSH solution, and 18.533 g (228 moles on a NaOH basis) of a 49.21 mass % aqueous NaOH solution were charged. The temperature of the resulting reaction mixture was increased to 173° C. over a period of five hours in a nitrogen atmosphere while stirring, 27.300 kg of water was distilled, and the autoclave was then sealed. In this step, p-DCB distilled by azeotropy during dehydration was separated by the decanter, and returned to the autoclave as needed. A particulate anhydrous sodium sulfide composition was dispersed in p-DCB inside the autoclave after the completion of dehydration
Example
(Preparation Example 2) Preparation of Polyphenylene Sulfide Resin (A-2)
[0085]A PPS resin (hereinafter referred to as A-2) was obtained in the form of a white powder in the same manner as in Preparation Example 1 except that the process in which subsequently, the inner temperature was increased from 200° C. to 230° C. over a period of three hours, and after stirring was conducted at 230° C. for one hour, the inner temperature was increased to 250° C. and stirring was conducted for one hour was changed to a process in which subsequently, the inner temperature was increased from 200° C. to 230° C. over a period of three hours, and after stirring was conducted at 230° C. for 1.5 hours, the inner temperature was increased to 250° C. and stirring was conducted for one hour. The resulting polymer had a melt viscosity of 73 Pa·s and the non-Newtonian index of 1.07.
