Abstract
The invention pertains to certain copolymers (PEDEK/PEEK), comprising a majority of 'PEDEK'-type recurring units, which, thanks to the predominance of PEDEK-type units, their structural homogeneity and regularity, and absence of chlorinated end groups, possess a suitable molecular structure and crystallization behaviour so as to deliver improved mechanical properties and outstanding chemical resistance, and which are useful in numerous fields of endeavours, including notably in the oil&gas industry, and more specifically for the manufacture of parts used in oil and gas extraction systems.
