二元混合物分子式:CAS号:性质:两种不同的组分组成的混合物,挥发两种组分组成的液体混合牛 二元乙丙橡胶 EPM;ethylene propylene copolymer 最初工业化的以乙烯和丙烯通过溶液聚合得到的共聚物。外观为无色至乳白色固体。相对密度0.855~0.865。nD1.476~1.481。丙烯含量25%~50%。Tg-52~-59℃。门尼黏度20~85。分子量分布为中~宽,分子结构为直线型,支化少,分子链柔顺。由于是饱和聚合物,分子结构中无双键,只能用过氧化物等含自由基的硫化剂进行硫化,硫化速度较慢。由于三元乙丙橡胶的出现,二元乙丙橡胶的用量和产量都显著下降。目前产量仅占乙丙橡胶的10%,主要用于制造要求更高耐老化性能和耐腐蚀的制品或用于塑料改性。
