| titleOfInvention | Stabilized polyphenylene sulfide |
| abstract | PURPOSE: A polyphenylene sulfide low in content of acetone-soluble oligomer and content of nitrogen in oligomer and excellent in heat stability, prepared by reacting an alkali sulfide with a dihalobenzene in a polar organic solvent under a specified reaction condition. n CONSTITUTION: An alkali sulfide (e.g., sodium sulfide) and a dihalobenzene (e.g., p-dichlorobenzene) are subjected to a polymerization reaction in a polar organic solvent (e.g., N-methylpyrrolidone). In this reaction, the following measure are taken: the heat hystereis in the polymerization and recovery processes is decreased, the polymer concentration during the polymerization is about 14W 29%, a polymerization aid such as lithium acetate is used, and a filter is used when the polymerization system is introduced into water to reprecipitate the polymer or to wash off inorganic salts. In this way, there is produced a stabilized polyphenylene sulfide consisting mainly of a structure unit of the formula and having an acetone-soluble oligomer content of below 2% and a content of nitrogen in oligomer of below 1.5%. n COPYRIGHT: (C)1982,JPO&Japio |
