Disclosed is a composition comprising a polyamide composition comprising nylon-66 or nylon 66/6T, and optionally nylon-6, nylon-610, nylon-612, nylon-11, nylon-12, an ionomer composition comprising at least one ethylene acid copolymer wherein 30 to 90% of the total acid functionalities are neutralized to salts with a mixture of zinc cations and sodium or lithium cations, wherein the salts comprise from 20 to 90% equivalents of zinc; and optionally reinforcing filler. Articles prepared from the composition exhibit improved calcium chloride salt stress crack resistance over polyamide compositions not containing the ionomer.
