Abstract
(EN)
The present invention relates to a poly(biphenyl ether sulfone) resin which substantially comprises the repeating structure of formula (1). In analysis with an NMR device for examining solid samples in which a 13C spectrum is acquired using a Torchia pulse sequence and the delay period τ in the pulse sequence is changed to cause an attenuation in the signal intensity I(τ) corresponding to a chemical shift of 129 ppm, then the spin-lattice relaxation time T1L for long components which is calculated from the attenuation is 24 s or longer. [In formula (1), n is an integer of 1 or larger.]

La présente invention concerne une résine de poly(biphényl-éther-sulfone) qui comprend sensiblement la structure de répétition de formule (1). Lors de l'analyse avec un dispositif de RMN permettant d'examiner des échantillons solides dans lesquels un spectre de 13C est acquis à l'aide d'une séquence d'impulsions de Torchia et la période de retard τ dans la séquence d'impulsions est modifiée pour provoquer une atténuation dans l'intensité de signal I(τ) correspondant à un déplacement chimique de 129 ppm, alors le temps de relaxation de réseau de spin T1L pour des constituants longs qui est calculé à partir de l'atténuation est supérieur ou égal à 24 s. [Dans la formule (1), n représente un nombre entier supérieur ou égal à 1].
