聚醯亚胺树脂粉末之制造方法及热塑性聚醯亚胺树脂粉末;METHOD OF PRODUCING POLYIMIDE RESIN POWDER, AND THERMOPLASTIC POLYIMIDE RESIN POWDER

摘要

本发明提供一种聚醯亚胺树脂粉末之制造方法，包括以下步骤：使含有四羧酸二酐之四羧酸成分(A)与含有脂肪族二胺之二胺成分(B)在含有式(1)表示之伸烷基二醇系溶剂之溶剂(C)存在下反应。(Ra1为氢原子或碳数1～4之烷基，Ra2为碳数2～6之直链伸烷基，n为1～3之整数。) The present invention provides a method of producing a polyimide resin powder, the method including a step in which a tetracarboxylic acid component (A) containing a tetracarboxylic acid dianhydride and a diamine component (B) containing an aliphatic diamine are reacted in the presence of a catalyst (C) containing an alkylene glycol-based catalyst represented by formula (1).(Ra1represents a hydrogen atom or an alkyl group with a carbon number of 1 to 4, Ra2represents a straight-chain alkylene group with a carbon number of 2 to 6, and n is an integer of 1 to 3).
