Process for production of high to ultra-high molecular weight linear polyarylenesulfides. |
| 摘要 |
<p>By maintaining an arylenesulfide prepolymer with a melt viscosity of 5 to 3,000 poise at a temperature of 245 to 290 °C under a liquid-liquid two-phase separated state in a solvent for 1 to 50 hours, the molecular weight of said prepolymer is increased to a high to ultra-high value while the linearity of the polymer is retained.</p> |
