Zusammenfassung:	Novolak resins ere incorporated for enhancing the acid resistance of polyamide compositions. Polyamide compositions containing such novolak resins are useful for producing various plastic shaped articles, such as calibrated particles or injection-molded parts, and are particularly useful for the recovery of sludge, liquids, and gases present in underground reservoirs, especially in the field of hydrocarbon extraction such as crude oil or natural gas.
