生胶 天然橡胶是由栽培的橡胶树上割取的胶乳，经稀释、过滤、凝固、滚压、干燥等步骤加工而得的弹性固体。是以异戊二烯为主要成分的不饱和状态的天然高分子化合物、其结构式见图。n约为10000左右，分子量分布在10-180万之间，平均分子量70万左右。实际上天然橡胶是多种不同分子量的聚异戊二烯的混合体。橡胶烃含量约91％-94％，其余为少量的蛋白质、脂肪酸、糖分、灰分等，不含杂质的然橡胶透明而略带黄色。相对密度(20 ℃/4℃)0．93，Tg＝-70 ℃。加热到130-140 ℃完全软化，200 ℃左右开始分解，270 ℃则急剧分解。折射率1. 5195，溶解度参数δ＝7．9-8．1。溶于苯、甲苯、二甲苯、溶剂汽油、二硫化碳、四氮化碳、氯仿、松节油等。不溶于乙醇和丙酮。天然橡胶具有很好的弹性，伸长率大(1000％)、机械强度较高，门尼粘度较高，自粘性好，耐透气性较好，耐碱，不耐浓强酸。耐油、耐溶剂性差，耐老化性不佳。 天然橡胶贮存时可发生粘度和硬度增加的贮存硬化现象，低温易结晶，应贮存于阴凉、通风、温度为10-30 ℃的库房内，防止日晒，不可重压，贮存期1年。
