This polyethylene furanoate has an intrinsic viscosity of 0.95-1.50 dl/g. Said intrinsic viscosity is measured (the Huggins constant is defined as 0.32) at 30°C by using a Ubbelohde viscometer, after dissolving 0.25 g of the polyethylene furanoate in 50 ml of a solvent mixture of phenol/1,1,2,2-tetrachloroethane=50/50 (weight ratio). L'invention concerne un poly(furanoate d'éthylène) présentant une viscosité intrinsèque de 0,95-1,50 dl/g. Ladite viscosité intrinsèque est mesurée (la constante de Huggins est définie comme valant 0,32) à 30 °C à l'aide d'un viscosimètre Ubbelohde, après dissolution de 0,25 g du poly(furanoate d'éthylène) dans 50 ml d'un mélange de solvants phénol/1,1,2,2-tétrachloroéthane = 50/50 (rapport pondéral). 固有粘度が０．９５ｄｌ／ｇ以上１．５０ｄｌ／ｇ以下である、ポリエチレンフラノエート。ただし、前記固有粘度は、前記ポリエチレンフラノエート０．２５ｇをフェノール／１，１，２，２－テトラクロロエタン＝５０／５０（重量比）の混合溶媒５０ｍｌに溶解し、ウベローデ粘度計を用いて３０℃で測定される（Ｈｕｇｇｉｎｓ定数は０．３２とする）。
