Abstract
The invention relates to a method of enhancing the surface appearance of articles made from an impact modified composition of a compatibilized polyphenylene ether-polyamide resin blend. The impact modified composition contains from about 5% to less than 50% by weight polyphenylene ether resin with from about 0.7% to about 1.1% by weight of a non-polymeric aliphatic polycarboxylic acid or derivative thereof and from about 5% to about 15% by weight of an elastomeric block copolymer, and from about 45% to about 90% of a polyamide resin, wherein the polyamide resin has an amine endgroup to acid endgroup ratio of at least about 1.0, and wherein all weights are based on the total weight of the composition.
