Abstract

PURPOSE:A composition obtained by blending a mixture of a polyphenylene ether resin and a styrenic resin with an ammonium halide, having extremely improved flame retardance without damaging properties of both the resins. CONSTITUTION:100pts.wt. polymer composition consisting of a polyphenylene ether resin and a styrenic resin is blended with 0.05-15pts.wt., preferably 0.1- 10pts.wt. ammonium halide. Poly(2,6-dimethylene-1,4-phenylene)ether, or a copolymer of 2,6-dimethylphenol and 2,3,6-trimethylphenol is used as the polyphenylene ether resin, and rubber midified polystyrene having high impact resistance, or styrene/acrylonitrile/butadiene terpolymer as the styrenic resin. Ammonium bormide or ammonium chloride is preferable as the ammonium halide.

Polymer compositions of polyphenylene ether, LT fat, and styrene resin have excellent mechanical properties, thermal properties, electrical properties, etc., and have good processability (such as home appliance parts, power distribution parts, automobile parts, and precision machinery parts). It is widely used for various purposes, and its demand has increased significantly in recent years, making it a useful material.

On the other hand, as one of the performance requirements of the industry for resins,
One example is flame retardancy. As seen in the UL standards in the United States, regulations on the flammability of resins are becoming increasingly strict, and compliance with these regulations is required, and polymer compositions of polyphenylene ether resins and styrene resins are no exception.

In order to meet this demand, aromatic phosphate esters were blended into the polymer composition (Japanese Patent Publication No. 53-418
, JP-A-53-73248), organic halides, or combinations of organic halides and antimony trioxide (JP-A-48-7945, JP-A-51-74)
038. Although some techniques have been published, such as one containing %P (1989-128946) and elemental phosphorus (USP 3663654), none of them can be said to be sufficient. In other words, there is a decrease in heat resistance when aromatic phosphate esters are used, a decrease in impact resistance when organic halides and antimony trioxide are used, and workability is affected because antimony trioxide is a deleterious substance surrounding pharmaceuticals. No flame retardant has been developed that is fully satisfactory, such as red coloration of the resin when elemental phosphorus is used, and the excellent performance of a polymer composition of polyphenylene ether resin and styrene resin has not yet been developed. It's not a loss (but it's economically necessary to make it flame retardant).

It is preferable to use 30 to 70 parts by weight of the styrene resin. If the polyphenylene ether resin is 90 parts by weight or more, the processability of the mixed composition of the resin and styrene resin will be extremely reduced, making it impractical (and if the styrene resin is 90 parts by weight or more, the heat distortion temperature will be insufficient There is nothing satisfying about 7j.

In addition, in the present invention, 0.05 to 15 parts by weight of ammonium halide is blended into 100 parts by weight of the polymer composition of polyphenylene ether type a fat and styrene resin, but if the amount is less than 0.05 parts by weight, it will not be added to the resin. Flame retardance cannot be imparted, and if the amount exceeds 15 parts by weight, the appearance of the molded product becomes poor when the resin is processed, and the impact resistance is extremely reduced, which is undesirable. It is more preferably added in an amount of 0.1 to 10 parts by weight per 100 parts by weight of the polymer composition of polyphenylene ether resin and styrene resin.
