Blends containing EPDM or rubber-modified vinyl aromatic polymers containing tutadiene, which is extremely high at ~350°C and are susceptible to thermal deterioration, or blends containing ethylene-vinyl acetate copolymers with low heat resistance, cannot be molded. Thermal deterioration progresses during the process, and sufficient improvement effects cannot be obtained.

からである。This is because if the polyetherimide content is more than 99% and the ethylene-butene-1 copolymer content is less than 1%, the desired effect of improving impact resistance will be insufficient, and if the polyetherimide content is less than SOW. This is because if the ethylene-butene-1 copolymer content exceeds 50%, the heat resistance and rigidity, which are characteristics of polyetherimide, will be significantly reduced, which is undesirable.
