2. Description of the Related Art Aromatic polysulfone resins have excellent characteristics such as heat resistance, mechanical strength and flame retardancy, and are widely used as engineering plastics in the field of metal replacement. In recent years, the resin has been increasingly used in the field of electric and electronic components, for example, as a socket-related material such as a burn-in socket and a PGA socket. In this type of application, good flowability of the resin is important for obtaining a good molded product because the product shape is complicated. For the purpose of improving the general fluidity of the resin, alloying with a resin having lower heat resistance than the resin has been widely studied.
JP-A-6-37896 discloses aromatic polysulfone resin and A
Japanese Patent Application Laid-Open No. 53-129248 discloses an alloy with a BS and an alloy with a polyamide resin. However, in these systems, although the fluidity is improved, there is a problem that the weld strength, heat resistance and thermal stability are inferior.
Alloys of aromatic polysulfone resins and polyphenylene sulfide resins have also been studied. For example, Tokiko Sho 6
No. 0-11063. However, conventionally, when molding at a high temperature such as the molding temperature of a porsulfone resin, the thermal stability of the polyphenylene sulfide resin is poor, and there are phenomena such as deterioration of fluidity, which is not practical.

[0010] The outline of the method for producing a polyphenylene sulfide resin described in JP-A-5-222196 is described below. Under an inert gas atmosphere, N-methyl-
Dehydration or water addition is performed as necessary so that the water content of the alkali metal sulfide such as sodium sulfide in the amide solvent such as 2-pyrrolidone becomes a predetermined amount. The water content is 0.5-2.
It is preferably 5 moles (per mole of alkali metal sulfide). If it is less than 0.5 mol, the reaction rate is too fast,
Undesirable reactions such as side reactions occur. If the amount exceeds 2.5 moles, the reaction rate is reduced, and the amount of by-products such as phenol increases during filtration after the reaction, and the degree of polymerization does not increase. The halogen-substituted aromatic compound may be put into the reaction system from the beginning, or may be added after the completion of dehydration.
The amount used is 0.9 to 1 mol of the alkali metal sulfide.
A range of 1.1 moles is desirable for obtaining high molecular weight polyphenylene sulfide resins. Cooling of the gas phase during the reaction
In the case of a one-stage reaction at a constant temperature, it is desirable to carry out the reaction from the start of the reaction, but it is necessary to carry out the reaction at least in the middle of raising the temperature to 250 ° C. or lower. In a multi-stage reaction, it is desirable to perform cooling from the first-stage reaction, but at least
It is preferable to carry out the reaction while the temperature is rising after the end of the step reaction.
The degree of the cooling effect is usually the most suitable index of the pressure in the reactor. The absolute value of the pressure varies depending on the characteristics of the reaction vessel, the stirring state, the water content in the system, the molar ratio of the halogen-substituted aromatic compound to the alkali metal sulfide, and the like. But,
If the pressure in the reactor is reduced as compared with the case where the reactor is not cooled under the same reaction conditions, the amount of reflux increases, which means that the temperature at the gas-liquid interface of the reaction solution has decreased. It is considered that the degree of the decrease indicates the degree of separation between the layer having a high water content and the layer having no water content. Therefore, cooling must be performed to such an extent that the internal pressure of the reaction vessel is lower than that in the case where cooling is not performed. The degree of cooling can be appropriately set by those skilled in the art according to the equipment used, operating conditions, and the like.

The oligomer content is the amount of a substance represented by weight% of a substance mainly composed of a low-molecular-weight polyphenylene sulfide resin, which is eluted by extraction with methylene chloride, based on the polyphenylene sulfide resin before extraction. The specific method for quantifying the amount of oligomer is a value determined as follows. 4 g of polyphenylene sulfide resin powder is added to 80 g of methylene chloride, soxhlet extraction is carried out for 4 hours, then cooled to room temperature, and the extracted methylene chloride solution is transferred to a weighing bottle. Further, the container used for the above-mentioned extraction is washed three times with a total of 60 g of methylene chloride, and after collecting the washing liquid, it is put in the weighing bottle. Next, the mixture was heated to about 80 ° C. to evaporate and remove the methylene chloride in the weighing bottle. The value obtained by subtracting the tare of the weighing bottle from the weight of the weighing bottle is divided by the weight of 4 g of the polyphenylene sulfide resin, and multiplied by 100 is the oligomer content (% by weight). In order to suppress the oligomer content to 1% by weight or less, in the production process of the polyphenylene sulfide resin, a slurry-like polyphenylene sulfide resin having a sufficiently high molecular weight (preferably having a weight average molecular weight in the range of 5,000 to 60,000, More preferably, it is preferably washed in an organic solvent, followed by washing with water. In the present invention, both washing in an organic solvent and washing with water may be performed, or if the oligomer content can be reduced to 1% by weight or less, either washing in an organic solvent or washing with water is used. It is permissible to perform only the cleaning method.

When the terminal of the polyphenylene sulfide resin is less than 30% of the SH group with respect to the SX group (X is an alkali metal such as Na, K, Li, Rb or Cs or hydrogen), a branched structure occurs in the polyphenylene sulfide resin.

EXAMPLES The present invention will be specifically described below with reference to examples, but the present invention is not limited to these examples. The measurement and evaluation of the physical properties of the resins in Examples and Comparative Examples were performed in the following manner. (1) Spiral flow Injection molding was performed at a resin temperature of 330 ° C., 350 ° C. and 370 ° C., and an injection pressure of 1500 kg / cm 2 using a spiral flow mold having a mold temperature of 150 ° C., a width of 10 mm and a thickness of 1 mm. The flow length was measured. The longer the flow length, the better the moldability. (2) MI retention test MI was measured at a load of 2.16 kgf and a temperature of 400 ° C in accordance with JIS-K7210. In addition, in normal measurement, measurement is started 6 minutes after the resin is put into the cylinder,
The measurement was also performed with the measurement start time extended to 30 minutes. Also,
The ratio between the two values was taken as the MI retention ratio (MI retention ratio = MI value at 30 minutes retention / MI value at 6 minutes retention × 100).
The closer the MI retention is to 100, the better the thermal stability. When the MI retention rate is significantly lower than 100, it is highly possible that the gelation of the resin composition is progressing,
The viscosity of the resin tends to increase during injection molding, which is not preferable. When the MI retention rate is significantly higher than 100, the decomposition of the resin composition may be progressing, and a large amount of gas may be generated during injection molding, which may cause insufficient filling or silver, which is not preferable. (3) Tensile strength Based on JIS-K7113. Here, both those with and without a weld at the center of the test piece were evaluated. The ratio between the two values was taken as the tensile strength retention rate (tensile strength retention rate = tensile strength of welded test specimen /
Tensile strength of test piece without welding × 100). The closer the tensile strength retention rate is to 100, the better the weld strength. (4) Deflection temperature under load Based on JIS-K7110. The bending stress is 18.56
Kg / cm 2 . The higher the deflection temperature under load, the better the heat resistance.
