| titleOfInvention | Process for preparing high molecular weight polyarylene sulfide copolymer |
| abstract | The present invention relates to a method for producing a high molecular weight polyarylene sulfide copolymer, and more particularly, to a polyhalogen aromatic compound and a polyhalogen aromatic in a solution dissolved by adding alkali metal sulfide and water containing crystal water to an organic polar solvent. The copolymerization of sulfone compounds increases the solubility in solvents and prevents premature precipitation of growing polymer chains, thereby increasing the molecular weight and glass transition temperature, eliminating the need for heat curing after polymerization, and having low melting temperature. It relates to a method of manufacturing. |
