The influence of a wide range of concentrations (0.1–40 mass%) of Na(K)I on both the thermal behaviour and melt indexes of polyoxyethylene (POE) in a broad temperature interval was investigated by combined dynamic thermal analysis and with an extrusion plastometer. It was found that addition of 2–5 mass% of alkali salts resulted in the optimum thermal stability of POE and increased the melt index...
