Abstract
Polyphenylene ether/rubber modified polystyrene compositions are uniquely suitable for flow molding large, e.g., 10 pounds or more, parts when the rubber modified polystyrene contains at least 12 percent by weight of particulate rubber, the rubber particles have an average diameter of greater than about 3 microns, and the compositions have an R* value of greater than about 16. R* is the ratio of the low shear rate viscosity to the high shear rate viscosity at the optimum processing temperature.
