ている。However, although molded products made of PPS exhibit excellent mechanical properties in the form of amorphous materials, when placed in a high-temperature atmosphere above its glass transition temperature, especially above 120'C, e.g.
This has the disadvantage that crystallization progresses rapidly, resulting in a significant decrease in mechanical properties and elongation at break, resulting in extreme brittleness.

撃性の改善効果が十分でないという問題があった。On the other hand, in order to improve the brittleness of PPS, it is widely used to strengthen it by adding a reinforcing agent such as glass fiber to PPS. Not only does the reinforcing agent stand out, impairing its smoothness and increasing its specific gravity, but also the matrix resin, pps, is extremely brittle, so reinforcing agents that do not inhibit molding processability in injection molding, etc. (Usually, there was a problem that the effect of improving mechanical strength, particularly impact resistance, was not sufficient if only 30 to 40% by weight was blended.

るのは適当でな（１。In order to obtain a PPS molded article having the novel characteristics of the present invention, it is first necessary to subject the pps powder, such as powder, chips, pellets, etc., to the patented heat treatment prior to molding. This heat treatment is a process in which the pps powder and granules are exposed to the presence of oxygen (at least once in an atmosphere at a temperature higher than the melting point of pps), and the heat treatment temperature is set to higher than the melting point of pps. Setting this value not only means to shorten the time required for processing, but also to give the desired new properties to pps. It is impossible to obtain a molded product with a crystallization peak temperature of 160°C or less.The upper limit of the heat treatment temperature is approximately 450°C, and it is inappropriate to set it higher than necessary (1).

。It is also an essential IP condition to perform heat treatment in the presence of oxygen, and when heat treatment is performed under reduced pressure or in an inert if soot atmosphere such as nitrogen, the pps crystal peak temperature should be increased to 160°C.
It is impossible to reduce the temperature to below ℃, and the purpose of the present invention is not achieved. The heat treatment time can be adjusted depending on the heat treatment temperature, and the treatment temperature may be as short as j', but depending on the treatment temperature and treatment The combination of times should be set so that the peak crystallization temperature of PPS is 160 C or lower, and if the heat treatment is stopped when the peak crystallization temperature is 160 C or higher, the effect of improving the tensile elongation at break will be It is not possible to obtain a molded article with a sufficient temperature.The term "crystallization peak temperature of 160° C. or lower" as used in the non-invention also includes a case where the crystallization peak temperature is substantially no longer observed as the heat treatment progresses.
