| titleOfInvention | High molecular weight polyphenylene sulfide resin and manufacturing method and use thereof |
| abstract | The present invention relates to high molecular weight polyphenylene sulfide resins and methods for their preparation and use. The present invention uses a sulfur-containing compound and a halogenated aromatic compound as raw materials, performs a polycondensation reaction using a basic compound and a fatty acid as a polycondensation auxiliary agent, and obtains a primary product of polyphenylene sulfide after purification treatment, and also this poly The primary product of phenylene sulfide is reacted with a chain extender at high temperature to produce a high molecular weight polyphenylene sulfide resin. The production method of the present invention has the characteristics of selectively and controllably producing polyphenylene sulfide resins having high yield and low cost and having different melt viscosities and molecular weights, and the obtained polyphenylene sulfide resins are excellent in heat resistance. The high heat-stable linear high molecular weight polyphenylene sulfide resin obtained in the present invention is used for the production of plate materials, pipe materials, and bars, and can be subjected to mechanical processing such as cutting, polishing, polishing, and drilling like metal, and also fibers, It is also used in the manufacture of membranes and films, and is particularly useful in fields such as automobile parts, electronic/electrical devices, chemical and mechanical industries. |
