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.

The present disclosure provides a thermoplastic resin composition having high rigidity and a low coefficient of linear thermal expansion and a molded article including the same. The thermoplastic resin composition includes a first propylene-ethylene copolymer, a second propylene-ethylene copolymer, a thermoplastic elastomer, an inorganic filler, and a sodium-phosphate-based nucleating agent as appropriate, and thus a molded article produced therefrom can exhibit improved mechanical rigidity, impact resistance, and dimensional stability. Even when formed to a low thickness for weight reduction, the molded article can be imparted with excellent processability, high tensile strength, a high flexural modulus, and high impact strength.
