    摘要: Disclosed is a composition comprising polyamide comprising nylon-6 and optionally nylon-6,66, nylon-66, nylon-610, nylon-612, nylon-11, nylon-12 and an ionomer comprising an ethylene carboxylic acid copolymer, wherein 30 to 90% of the total carboxylic acid functionalities are neutralized to salts with a mixture of zinc cations and cations of a second metal selected from Group 1 of the Periodic Table of the Elements wherein the salts comprise from 20 to 90% equivalents of zinc. Articles prepared from the composition have improved salt stress crack resistance when exposed to zinc chloride solutions.
