Abstract: The compatibility between four phenolic antioxidants and PE(7047)was studied quantita-tively and qualitatively by weight increased and FT-IR spectra.The results show that hindered phenolic antioxidants have poor stationarity on compatibility with PE in high temperature,the effect of concentration on the compatibility of hindered phenolic antioxidant and PE is little.All the four antioxidants have good compatibility with PE resin,in the range of additive amount,and BHT is the best,1098 and 1076 followed,1010 in the end,and the effect of molecular structure on compatibility had been discussed briefly.

摘要： 同时采用质量增重法和傅里叶红外光谱法(FT-IR)定量和定性研究了4种常用受阻酚类抗氧剂与 PE(7047)树脂的相容作用,结果表明,高温时受阻酚类抗氧剂与PE的相容作用平稳性较差,而浓度对4种受阻酚类抗氧剂与PE的相容作用影响较小。4种抗氧剂在添加量范围内与PE树脂均具有良好的相容性,且以BHT 最优,其次为抗氧剂1098和1076,最后为抗氧剂1010,并简要探讨了分子结构对相容作用的影响。
