摘要：
An improved method for dispersing an inorganic pigment uniformly in polyphenylene ether resins. A polyphenylene ether composition having an inorganic pigment uniformly dispersed therein is obtained by intimately mixing a polyphenylene ether resin and the inorganic pigment in a weight ratio of from 0.5:1 to 2:1 by a high-speed mixer to form a pre-blend, and then mixing the pre-blend intimately with a polyphenylene ether in a conventional mixer such as an extruder. The pre-blend can also be uniformly dispersed in a mixture of the polyphenylene ether with polystyrene, a styrene/butadiene copolymer, a styrene/butadiene/acrylonitrile terpolymer, or a rubber-modified high impact polystyrene.
