ポリアリ−レンスルフィド樹脂の製造方法

Method for producing polyarylene sulfide resin

Abstract

【課題】反応容器中に有機極性溶媒及び固形物質が共存する所謂不均一系で、スルフィド化剤とポリハロ芳香族化合物とをアルカリ触媒下に反応させてPAS樹脂を製造する際に、該反応容器の腐食と摩耗を良好に防ぎ、反応容器の減肉を防止できるPAS樹脂の製造方法を提供すること。 【解決手段】反応容器中にN−メチルピロリドン及び固形物質が共存する系で、アルカリ金属硫化物とジクロルベンゼンとを反応させるポリアリーレンスルフィド樹脂の製造方法であって、前記反応容器の接液部がジルコニウムで構成されている装置を用いる。 【選択図】なし
<P>PROBLEM TO BE SOLVED: To provide a method for producing a polyarylene sulfide resin (PAS resin) by which the corrosion and abrasion of a reaction vessel are prevented well to prevent the reduction of the thickness of the reaction vessel when producing the PAS resin by reacting a sulfidation agent with a polyhalo aromatic compound in the presence of an alkali catalyst in a so-called heterogeneous system in which an organic polar solvent and a solid material coexist in the reaction vessel. <P>SOLUTION: The method for producing the polyarylene sulfide resin by reacting an alkali metal sulfide with dichlorobenzene in the system in which N-methylpyrrolidone and a solid material coexist in the reaction vessel uses an apparatus wherein the wetted part of the reaction vessel is constituted of zirconium. <P>COPYRIGHT: (C)2008,JPO&INPIT
