However, these organic phosphite compounds may hydrolyze during long-term storage or under high temperature and high humidity to lose the stabilizing effect. JP-A-52-22042 or JP-A-56-1137
Japanese Patent Publication No. 90 proposes to suppress such hydrolysis by adding an amine compound. Further, JP-A-3-68638 suppresses hydrolysis of diarylpentaerythritol diphosphite by adding an alkali metal and / or alkaline earth metal oxide, a metal soap, or an alkali metal salt of an inorganic acid. It is suggested to do so. Further, di (2,6-di-tert-butyl-4-methylphenyl) pentaerythritol diphosphite described in JP-A-56-152863 is a compound having excellent processing stability and anti-coloring effect. However, since its hydrolysis resistance is low, JP-A-62-223290 proposes to add triisopropanolamine in order to prevent the hydrolysis.

However, although these various hydrolysis inhibitors are effective, they are not sufficient, and the effect of imparting processing stability to the hydrolysis-protected organic phosphite compound is not satisfactory either. There has been a demand for an organic phosphite compound having excellent hydrolysis resistance and an excellent effect of imparting processing stability.

[Means for Solving the Problems] As a result of intensive studies made by the present inventors in view of the present situation, a specific di (2,6-ditertiaryalkyl-4-methylphenyl) pentaerythritol diphosphite was obtained. When hydrotalcites are added, it not only improves the hydrolysis resistance of the di (2,6-ditertiary alkyl-4-methylphenyl) pentaerythritol diphosphite, but also improves the processing stability of the resin. Di (2,6-ditertiary alkyl-4-methylphenyl)
The present invention has been found to be significantly improved as compared with the case where pentaerythritol diphosphite is used alone or the case where hydrotalcite is added individually to a resin, and the present invention has been completed.

(Results) As is clear from the results of each Example, the specific (2,6-ditertiary alkyl-) used in the present invention was used.
With respect to the 4-methylphenyl) pentaerythritol diphosphite compound, the addition of hydrotalcites significantly improved the hydrolysis resistance as compared with the case where other hydrolysis inhibitors were added. As is clear from the reference example, the processing stability of the synthetic resin to which the composition of the present invention was added was also improved. Such properties were also observed when mixed with other phosphite compounds. Such a phenomenon that improves the processing stability was not observed in the amine compound having a hydrolysis preventing effect. Moreover, bis (2,4-ditertiary butylphenyl) pentaerythritol diphosphite having a similar structure to the di (2,6-ditertiary alkyl-4-methylphenyl) pentaerythritol diphosphite compound used in the present invention. Then, although hydrotalcites were effective in preventing hydrolysis, no particular effect was observed in processing stability. Further, di (2,6-ditertiary alkyl-4-as used in the present invention
When the methylphenyl) pentaerythritol diphosphite compound and the hydrotalcites are added to the resin separately, the processing stability is inferior as compared with the case where the mixture of the composition of the present invention is added in advance. It became clear (from Comparative Reference Examples 1-n and 2-m).
From the above, the organic phosphite composition of the present invention showed a specific processing stabilizing effect on synthetic resins.
