聚异丁烯聚异丁烯polyisobutene异丁烯的聚合物。英文缩写PIB。结构式为聚异丁烯耐老化、耐臭氧、耐多种无机酸、碱、盐和极性介质的侵蚀；有极好的绝缘性和气密性。缺点为易冷流，可添加填充物或其他橡胶加以改善。聚异丁烯是饱和聚合物，因此不能硫化，如与少量（＜5％）双烯烃共聚，即为可硫化的丁基橡胶（IIR）。异丁烯可在低温下高速进行正离子聚合，催化剂为无机酸（硫酸、磺酸、过氧酸或硅酸盐）时，室温以下聚合可得低分子量聚合物（分子量几百～几万），若用路易斯酸（BF3、AlCl3等）为催化剂并加少量水或酸作助催化剂，在低温（－78～－100℃）下聚合，可制备高分子量（150万～200万）聚合物。此外也可采用齐格勒-纳塔催化剂进行配位聚合或辐照聚合。低分子量聚异丁烯作润滑剂的增粘剂，以适应高温润滑需要。高分子量聚异丁烯与聚乙烯共混作电缆涂层，还可用于防水胶布、防水石、蜡纸以及热熔胶中。
