る他、コーティング材料等にも使用できる。The compatibilizer and resin composition of the present invention have the following effects. A styrene resin or an aromatic polyether resin and a resin having reactivity with an amino group are polymerized.
At the time of blending, by using the compatibilizing agent of the present invention, blending can be performed without lowering the physical properties of the resin such as impact resistance and fluidity. Further, the resin composition of the present invention has a plurality of excellent properties that cannot be obtained alone, such as impact resistance, fluidity, heat resistance, and moldability. When modifying a resin with a conventional polymer blend, it is necessary to increase the compatibility of the resins with each other by some method, but since the compatibility is not sufficient, the impact resistance is insufficient and the polymer blend In many cases, the effect of modification by the above was not exhibited. Since the resin composition of the present invention using the compatibilizing agent of the present invention exhibits the above effects, it is useful not only for various molding materials but also for coating materials and the like.
