Melt stabilization of poly (arylene sulfide sulfone) S. |
| 摘要 |
<p>Improved poly(arylene sulfide sulfone)s are prepared by contacting these polymers with a zinc source, optionally first with an alkali metal base, for a period of time sufficient to incorporate enough zinc cations to improve the melt stability of the polymers. The polymer can be subsequently cured to increase molecular weight.</p> |
