Title:
ポリアリーレンエーテルケトン樹脂及びその製造方法、並びに成形体
Document Type and Number:
Japanese Patent JP6819842
Kind Code:
B2
Abstract:
Provided is a poly(arylene ether ketone) resin which inhibits reactions such as molecular weight extension and crosslinking in a high-temperature molten state and which is excellent in melt viscosity stability and molding processability. The poly(arylene ether ketone) resin contains an alkylsulfonyl group represented by general formula (1). In the formula, R is an alkyl group containing one to four carbon atoms.
