PEG 聚乙二醇又称聚乙二醇醚，简称PEG，结构式为HO(CH2CH2O)nH，根据分子量大小不同，可从无色透明粘稠液体(分子量200～700)到白色脂状半固体(分子量1000～2000)直至坚硬的蜡状固体(分子量3000～20000)，相对密度(20℃／20 ℃)1．12～1.15。作为增韧利用的聚乙二醇主要是分子量200～600的室温下为无色透明的粘性液体，无味。易溶于水，溶于甲醇、乙醇、丙酮、醋酸乙酯、苯、甲苯、二氯乙烷、三氯乙烯等．不溶于脂肪烃。对酚类溶解能力强，当皮肤上附有苯酚、甲酚时，可用分子量约400的聚乙二醇除去。与硝酸纤维素、松香、酪阮可以混合．但对一般的合成树脂不溶解，对橡胶也不溶胀。吸湿性大。聚乙二醇在正常条件下是很稳定的，但在120 ℃或更高温度下能与空气中的氧发生氧化作用。加热至300 C产生断裂或热裂解。聚乙二醇不挥发．闪点高，对金屑无腐蚀性。无毒，对眼睛和皮肤无明显刺激，LD5033000～43000mg/kg。 用作环氧树脂和聚乙烯醇的增韧剂。 贮存于干燥的库房内，远离火源。
