Abstract
A process for reducing lip buildup during an extrusion of a polyphenylene ether composition comprises adding a linear low density polyethylene compound to the composition, wherein the amount of linear low density polyethylene compound is less than or equal to about 10 percent by weight based on the amount of polyphenylene ether compound in the composition.
