る。2. Description of the Related Art Halogen-containing resins such as vinyl chloride resin undergo a decomposition reaction due to hydrogen halide generated in the molecular chain due to heating or light during molding and use, and as a result, the resin is Alterations such as coloring, discoloration, and deterioration of mechanical strength are observed. In order to avoid such drawbacks, stabilizers such as composite metal soaps are added. As the stabilizer for the halogen-containing resin, zinc-based, lead-based, alkaline earth metal-based or organotin-based stabilizers are mainly used. Although these stabilizers capture hydrogen halide generated during molding and use of the halogen-containing resin,
Because it changes to metal chloride, neither long-term thermal stability is sufficient, especially when zinc, alkaline earth metal-based stabilizer is used, which brings about coloring accompanying zinc burning during molding, etc. There is a strong demand for improved thermal stability.

A partial esterification product of a polyol having OH and a single type of fatty acid is blended with the halogen-containing resin together with the various stabilizers. However, among these stabilizing aids, polyol has a high melting point and has poor dispersibility in a halogen-containing resin.
A product molded from a halogen-containing resin composition containing these polyols has a drawback that impact strength is lowered. Further, a partial esterification product of a polyol having a neopentyl type skeleton and a fatty acid has a high degree of esterification (that is, a low hydroxyl group content), but exhibits good dispersibility in a halogen-containing resin, but has a thermal stability. Extremely bad. On the contrary, when the degree of esterification is low (that is, the content of hydroxyl group is high), unreacted polyol remains, so that the above-mentioned drawbacks are found in the blending of polyol. Therefore, in applying such a stabilizing aid to a halogen-containing resin, a complicated step of separately removing unreacted polyol from the partial esterification product and isolating a reaction product having a particularly low average esterification degree It is the actual situation that has gone through.

For example, a mixed linear saturated fatty acid having 12 to 28 carbon atoms and having the following fatty acid composition can be preferably used. If a straight chain saturated fatty acid having less than 12 carbon atoms, a side chain saturated fatty acid, an unsaturated fatty acid or the like is used, the melting point of the partially esterified product with the neopentyl type polyol is lowered, which is not preferable in terms of workability.

It can be easily produced according to a usual esterification reaction in which a dehydration reaction is carried out at a temperature of several hours. If necessary, a suitable organic solvent, catalyst, etc. may be used without any problem. By changing the ratio of the mixed fatty acid to the polyol as the raw material used, partial esterification products having various esterification rates can be obtained.

好ましくない。In the present invention, it is important that the partial esterification product thus obtained has an esterification rate of 30 to 70%. That is, it is necessary that the total number of hydroxyl groups of the polyol used as a raw material is esterified within the above range. When the esterification rate is less than 30%, the dispersibility in a halogen-containing resin is poor, and the generation of blooms or bleeds after the resin molding, which is caused thereby, significantly reduces the commercial value of the molded resin.
When it exceeds%, the thermal stability is drastically reduced, which is not preferable.

Excellent long-term thermal stability. That is, in the present invention, the distribution of the mixed fatty acid is set to 12 to 2 carbon atoms.
By setting a wide range of 8, the dispersibility in the halogen-containing resin is particularly improved. Further, the higher the content of the partial esterification product having a lower esterification rate (higher hydroxyl group content), the more remarkable the heat stabilizing effect of the halogen-containing resin.
