。(Prior art and its problems) Poly7-ethylene ether resin is a well-known resin and is a high-performance engineering plastic having a relatively high melt viscosity and a high softening point. However, the polyphenylene ether resin itself is poor in chemical resistance, particularly in organic solvent resistance, so its uses are currently limited. Furthermore, because of its high melt viscosity, it is difficult to mold this resin alone, and its impact strength is also low.

示している。(Evaluation of chemical resistance) A bending strain of 1.0% was applied to the tensile test piece, and F paper was pasted with sellotape on the part where the strain stress was maximum, and then a wax strip of kerosene grass was applied to the FiE part ( After applying oil (or salad oil, launa oil) and leaving it at room temperature for 48 hours, a tensile test was conducted to evaluate the chemical resistance based on the retention rate of elongation at break. The higher the retention rate, the better the chemical resistance.
