Process for producing poly(arylene sulfide) of reduced alkali metal content |
| 摘要 |
Disclosed herein is a novel process for producing a substantially linear PAS which contains an electrolytic alkali metal of not more than 50 ppm, shows a melt viscosity of 10 to 300 poise (measured at 310 DEG C. and at a shear rate of 10,000 sec-1) and is suitable as a resin for packaging electronic parts.
