Abstract
(EN)
The present invention relates to: a poly(biphenyl ether sulfone) resin which is substantially composed of a repeating structure of formula (1), and which is configured such that the mass average molecular weight Mw based on polystyrene standards and the melt viscosity μ at the temperature of 350°C satisfy formula (6) and formula (7); and the like. (In formula (1), n represents an integer of 1 or more.) (6): 60,000 ≤ Mw ≤ 90,000 (7): 0.0906 × Mw - 4,930 ≤ μ ≤ 3,500
(FR)
La présente invention concerne : une résine de poly(biphényl-éther-sulfone) qui est sensiblement composée d'une structure de répétition de formule (1), et qui est conçue de sorte que la masse moléculaire moyenne en masse Mw par rapport à des standards de polystyrène et la viscosité à l'état fondu μ à la température de 350 °C satisfont à la formule (6) et à la formule (7) ; et analogues. (Dans La formule (1), n représente un nombre entier supérieur ou égal à 1). (6) : 60 000 ≤ Mw ≤ 90 000. (7) : 0,0906 × Mw - 4 930 ≤ μ ≤ 3 500.
