Title:
POLY(BIPHENYL ETHER SULFONE) RESIN AND MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2020/066888
Kind Code:
A1
Abstract:
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
