| titleOfInvention | A kind of synthetic method of high-molecular linear polyphenyl thioether |
| abstract | The invention provides the method for a kind of high-molecular linear polyphenyl thioether synthesis.Comprise the steps: that (1) sodium sulphite, santochlor and phosphoric acid salt are in a solvent in 170-230 DEG C, carry out one section of prepolymerization reaction, reaction 1-4h, generates prepolymer; (2) at temperature 240-280 DEG C, under pressure 0.5-1.0Mpa condition, carry out two sections of polyreactions, reaction 2-5h, generates polymkeric substance; (3) after second-stage reaction terminates, add sodium sulphite, reaction 0.5-2h, generates the polyphenylene sulfide of high-molecular linear.Production technique of the present invention is reasonable, and technical qualification and resin quality have good repeatability, and whole technological process operation is comparatively stable, is applicable to technical scale and prepares polyphenylene sulfide. |
