聚1-丁烯系由高纯度1-丁烯在立体定向齐格勒-纳塔催化剂作用下聚合而成。其制备过程大致为：把经过脱水、脱氧的1-丁烯通入预先装有四氯化钛/三乙基铝[Al/Ti=1:1(摩尔比)]络合催化剂和乙烷溶剂的反应釜中，在室温和常压[或150℃和6.08Mpa（60atm）]的条件下进行聚合反应。在反应过程中不时地加入乙烷以稀释之，至反应终点出料，然后用乙醇使聚合产物中的催化剂失去活性，并洗涤，除净催化剂，即得具有等规结构、高结晶度的聚1-丁烯。目前已知它有5种晶型，从挤出机出来的熔融聚合物结晶时，生成亚稳定的晶型II，在室温和常压下放置5-10天陈化后，晶型II就会不可逆地转变稳定的晶型I。
近年来，芬兰Neste公司开发了一种低能耗的聚1-丁烯生产新工艺。聚合反应采用高活性齐格勒-纳塔配位聚合催化剂，简化了工艺流程，去掉了分离催化剂残渣和无规聚合物等工序。整个工艺流程只包括聚合、干燥和造粒三个步骤。在聚合反应中，可直生成高熔点、结晶形态稳定的晶型I聚合物。
