    • It is herein disclosed a process for stabilizing freshly prepared polyketone polymer comprising contacting the polymer with a sufficient quantity of a stabilizing agent such as an alkali metal iodide salt or an onium iodide salt of nitrogen, phosphorus, or arsenic in which the organic groups comprising the cation coordination sphere is shielded by aromatic substituents. The inventive process results in stabilized polyketone polymers having and exhibiting improved thermal oxidative stability properties. It is also disclosed a stabilized polymer composition comprising a major amount of a polyketone polymer and a minor amount of an onium iodide salt of nitrogen, phosphorus, arsenic or combination thereof in which the cation coordination sphere is shielded by aromatic substituents.
    • 本文公开了一种稳定新鲜制备的聚酮聚合物的方法,包括使聚合物与足量的稳定剂如碱金属碘化物盐或氮,磷或砷的碘鎓盐接触,其中含有 阳离子配位球被芳族取代基遮蔽。 本发明的方法产生具有和表现出改善的热氧化稳定性性质的稳定的聚酮聚合物。 还公开了一种稳定的聚合物组合物,其包含主要量的聚酮聚合物和少量的氮,磷,砷或其组合的碘鎓盐,其中阳离子配位球被芳族取代基屏蔽。
