摘　　要：针对高速纺丝油剂用丁醇聚醚主链氧化产生的有机过氧化合物会影响丁醇聚醚的结构和高速纺丝油剂的使用性能的问题,模拟丁醇聚醚生产、储存和使用过程条件,研究碱性、氧气以及高温对丁醇聚醚主链稳定性的影响。结果表明：碱性条件下生产有利于保持丁醇聚醚主链的稳定,氧气对丁醇聚醚主链稳定性的影响显著,有氧时丁醇聚醚的过氧化值会增加至189.7-226.6 mg/kg,氮气保护时丁醇聚醚的过氧化值增加幅度不大,维持在30 mg/kg左右。温度对丁醇聚醚主链稳定性影响显著,在210-230℃条件下丁醇聚醚过氧化值会增加至115.9-144.9 mg/kg。Butanol polyther used as high-speed spinning finishes,generates organic peroxy compounds due to the oxidation of main chain,which will influence its structure and high-speed spinning finishes＇ performances. The effect of alkaline,oxygen and high temperature on the main chain stability of butanol polyether was studied under production,storage and application conditions. The results demonstrated that alkaline condition is conductive to the stability of butanol polyether. The peroxide value of butanol polyether increased to 189. 7-226. 6 mg / kg in the presence of oxygen gas,while the peroxide value of butanol polyether increased marginally and the peroxide value is maintained at about 30 mg / kg in the absence of oxygen gas, which indicates that oxygen gas has a significant effect on its stability.Additionally,the polyether appeared to be more unstable at high temperatures,the peroxide value rose to115. 9-144. 9 mg / kg at the temperature of 210-230 ℃.
