Abstract:
A method for enhancing the surface appearance characteristics of articles formed from sheet made from a compatibilized polyphenylene ether resin/polyamide resin composition, wherein the method comprises:(a) melt-mixing in a first step, from about 35% to about 49% by weight polyphenylene ether resin with from about 0.8% to about 1.0% by weight of a non-polymeric aliphatic polycarboxylic acid or derivative thereof and from about 8% to about 12% by weight of an elastomeric block copolymer, wherein the elastomeric block copolymer is a di-block, tri-block, or a mixture of a di-block and a tri-block, wherein the copolymer comprises a polyarylene block, with from about 10% to about 15% by weight of polyamide resin wherein all weights are based on the total weight of the final composition, and(b) further melt mixing in a second step additional polyamide resin;wherein the total weight of the polyamide resin is from about 45% to about 55% by weight based on the total weight of the final composition; and wherein the polyamide resin is a nylon-6 resin, and wherein the polyamide resin has an amine endgroup to acid endgroup ratio of at least about 1.0.
