Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of recovering sludge, liquid or gas from an underground reservoir, said method comprising introducing a polyamide or polyamide composition having increased resistance to acids into an underground reservoir, said polyamide comprising hydroxyaromatic units and said polyamide composition comprising a polyamide comprising hydroxyaromatic units, wherein said hydroxyaromatic units are chemically bonded to the chain of the polyamide.…
