Abstract:
Provided are a device for continuously producing poly(arylene sulfide) (hereinafter, referred to as PAS) and a method for continuous PAS production with which resource savings, energy savings, and a reduction in equipment cost are rendered possible. The device for continuous PAS production according to the present invention includes a housing chamber for housing a plurality of reaction cells; wherein the housing chamber is supplied with at least an organic amide solvent, a sulfur source, and a dihalo aromatic compound. In the reaction cells, the sulfur source is polymerized with the dihalo aromatic compound in the organic amide solvent to form a reaction mixture. The reaction cells communicate with each other through a gas phase within the housing chamber. The reaction cells are sequentially connected, and the reaction mixture sequentially moves to each reaction cell.

Claim (Index 1):
A device for continuously producing poly(arylene sulfide), the device comprising a housing chamber configured to house a plurality of reaction cells,\n the housing chamber being supplied with at least: an organic amide solvent; at least one type of sulfur source selected from the group consisting of hydrogen sulfide, alkali metal sulfides, and alkali metal hydrosulfides; and a dihalo aromatic compound; a reaction mixture being formed by carrying out a polymerization reaction between the sulfur source and the dihalo aromatic compound in the organic amide solvent in at least one or more reaction cells, the reaction cells being mutually communicated through a gas phase within the housing chamber, and the reaction cells being sequentially connected, and the reaction mixture being sequentially moved to each of the reaction cells.
