Abstract
The use of a polyamide including hydroxyaromatic units in order to increase the acid resistance of a polyamide composition is described. A polyamide composition comprising a polyamide that includes hydroxyaromatic units and use thereof for the manufacture of various plastic articles such as, for example, calibrated particles or injection-molded parts is also described. Such a composition is especially useful in the field of the recovery of slurries, liquids and gases present in underground reservoirs, and in particular in the field of the extraction of hydrocarbons, such as crude oil or natural gas.
