PURPOSE:To obtain a polyamide resin composition which can give a molding free of surface stickiness and rendered very flexible, by mixing a specified p- or o-hydroxybenzoic ester with a polyamide resin. CONSTITUTION:An ester of p- or o-hydroxybenzoic acid with a 12-22C branched alcohol (e.g., 2-ethyldecyl p-hydroxybenzoate) is added in an amount of 0.1-30 pts.wt. per 100pts.wt. polyamide resin. The plasticizer obtained by using said branched alcohol can give a molding free of surface stickiness, is lowly volatile and has a marked flexibilizing effect, so that a polyamide resin of excellent flexibility can be obtained. |
