ABSTRACT:
A polyphenylene ether copolymer produced by oxidative coupling of 60 to 99.9 mole percent of a phenol with 0.1 to 40 mol percent of an aniline. The inventive copolymer has improved heat resistance, shock resistance, and tensile strength. When used by itself or in a mixture with other polymers, such as polystyrene or ABS resins, the inventive product is useful as an excellent engineering material.
