Title:
MELT-PROCESSING MATERIAL AND MELT-PROCESSED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2022/244576
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a polyimide provided with high heat resistance and excellent melt flow properties, and a melt-processing material which contains said polyimide and has high heat resistance and excellent melt-processing properties. As a solution, the present invention provides a melt-processing material which contains a polyimide which has a repeating unit represented by general formula (1). (In the formula, R1 each independently represent a C1-6 straight-chain or branched-chain alkyl group, a C1-6 straight-chain or branched-chain halogenated alkyl group, or a halogen atom, m each independently represent 0, 1 or 2, and X represents a divalent chemical group which is represented by general formula (2).)
