重合体などを挙げることができる。In the composition of the present invention, a styrenic polymer having a substantially syndiotactic structure is used as one of its components, and this is because the phenyl groups present in the molecular chain alternate along the main chain. It is mainly composed of a styrene polymer or a substituted styrene polymer having a structure having a steric configuration, and this can be easily determined by 13C-NMR analysis. Examples of styrenic polymers having such a structure include polystyrene polymerized using a Ziegler catalyst and poly(alkylstyrene).
, poly(halogenated styrene), poly(alkoxystyrene), poly(benzoylstyrene), and copolymers containing styrene, alkylstyrene, and halogenated styrene as main components.

きる。The aromatic polyether polymer used as one of the components of the composition of the present invention is a polyether containing a divalent aromatic residue such as a phenylene group, a biphenylene group, or a naphthylene group in its main chain. The most preferred one is the general formula (wherein R1 and R2 are each a hydrogen atom, a halogen atom, an alkyl group, or an aryl group, and they may be the same or different from each other) Polymers and copolymers consisting of structural units represented by the above and graft copolymers of these and styrene compounds can be mentioned.

1の範囲である。The composition of the present invention must contain a styrene polymer having a substantially syndiotactic structure and an aromatic polyether polymer in a weight ratio of 1:LO to 10:l. It is. If the amount of the styrenic polymer having a syndiotactic structure is less than or greater than this, the improvement in heat resistance will be insufficient. A particularly preferred ratio of both is 1:4 to 4:
The range is 1.

の組成物を得ることができる。In the composition of the present invention, a compatibilizer is further added to the above-mentioned components in an amount of 1 to 20% by weight, preferably 2% by weight based on the total amount of the composition.
It is necessary to mix it in an amount of ~15% by weight. By using this specific amount of compatibilizer, even if a styrene polymer with a syndiotactic structure and an aromatic polyether polymer are simply blended, it is difficult to mix them, and phase separation is prevented during molding. This improves the problem of the fact that compositions consisting only of the two did not always give satisfactory results in terms of appearance and performance, and for the first time made it possible to uniformly and finely disperse one component in the other. , a composition with excellent appearance and physical properties can be obtained.
