And it relates to a molded article manufactured including the same.

Poly (arylene ether) resins are amorphous resins, which have excellent dimensional stability, insulation, heat resistance, and rigidity, and thus are widely used in various fields such as automobile parts and parts of electric and electronic products. However, poly (arylene ether) resin alone has poor workability due to high melt viscosity, and thus blends with polymers such as polyamide, polyolefin, and polystyrene to improve processability, and especially blends with polyamide resin. It is known that a resin composition having improved heat resistance and workability can be obtained. Therefore, the use of a modified poly (arylene ether) resin, which is a poly (arylene ether) / polyamide blend resin, is required in parts requiring high heat resistance. It is becoming. However, there are still many problems such as deterioration in appearance due to blending of poly (arylene ether) and polyamide, deterioration of dimensional stability and impact strength, and change of physical properties due to moisture. .

Accordingly, studies to solve the above problems are actively progressed, but the high specific gravity of polyamide, which is a fundamental problem of poly (arylene ether) / polyamide blending resin, and a large change in physical properties due to moisture have not been solved.
