Method for reducing release force of compatibilized polyphenylene ether-polyamide resin blend

摘要

The invention relates to a method of reducing the ejector force of articles made from an impact modified composition of a compatibilized polyphenylene ether-polyamide resin blend. The impact modified composition contains from about 10 % to less than 30 % 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 1 % to about 15 % by weight of an elastomeric block copolymer, and from about 1 % to about 15 % of a functionalized elastomeric olefin, and from about 45 % to about 90 % of a polyamide resin. The functionalized elastomeric olefin is preferably an EPR-graft-maleic anhydride or an EPDM-graft-maleic anhydride.
