Title:
POLY(ARYLENE ETHER KETONE) RESIN, PRODUCTION METHOD FOR SAME, AND MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2020/137420
Kind Code:
A1
Abstract:
Provided is a poly(arylene ether ketone) resin that has excellent moldability and melt viscosity stability and that suppresses reactions such as molecular weight extension and cross-linking, even when melted at high temperatures. A poly(arylene ether ketone) resin that has an alkyl sulfonyl group that is represented by general formula (1). In the formula, R is a C1–4 alkyl group.
