应用
异戊二烯在作为引发剂的仲丁基锂的存在下，可以与苯乙烯和甲基丙烯酸甲酯进行顺序的阴离子聚合，从而形成聚苯乙烯-嵌段-聚异戊二烯-嵌段-聚（甲基丙烯酸甲酯）（SIM）和聚异戊二烯-嵌段-聚苯乙烯-嵌段-聚（甲基） 甲基丙烯酸酯（ISM），两种不对称三嵌段三元共聚物。它也可用于聚苯乙烯-嵌段-聚异戊二烯（PS-b-PI）二嵌段共聚物的不对称合成。

Isoprene is one of the most abundant endogenous volatile organic compounds (VOCs) contained in human breath and is considered to be a potentially useful biomarker for diagnostic and monitoring purposes. However, neither the exact biochemical origin of isoprene nor its

Isoprene (2-methyl-1,3-butadiene) is emitted from many plants and it appears to have an adaptive role in protecting leaves from abiotic stress. However, only some species emit isoprene. Isoprene emission has appeared and been lost many times independently during the evolution
