ABSTRACT 1,3-butadiene (1,3-BD) is a building block produced mainly as a byproduct of the ethylene steam cracking process. However, due to the growing interest in sustainable technologies, there is also growing interest in manufacturing 1,3-BD from ethanol. For this reason, taking into account that the ethanol-derived 1,3-BD can contain oxygenated contaminants that are difficult to remove, the present manuscript investigates for the first time how the presence of low concentrations of some oxygenates (acetaldehyde, crotonaldehyde, 3-hydroxybutyraldehyde, acetone, water, ethanol, 1,3-butanodiol, 3-buten2-ol, crotyl alcohol, and 1-butanol) in the 1,3-BD monomer can affect polymerization reactions performed with the neodymium versatate catalyst and modify the characteristics of the obtained polybutadiene products. It is shown that the presence of oxygenated compounds can cause inhibitory effects on the course of the polymerization and modify the molar mass distributions and flow properties of the final products, although all analyzed samples presented the characteristic high-cis character of polybutadienes produced with the neodymium versatate catalyst.

含氧化合物对用叔碳酸钕进行的 1,3-丁二烯聚合的影响。第一部分：酒精、醛、酮和水

摘要 1,3-丁二烯 (1,3-BD) 是一种结构单元，主要作为乙烯蒸汽裂解过程的副产品生产。然而，由于对可持续技术的兴趣日益浓厚，人们对用乙醇制造 1,3-BD 的兴趣也越来越大。出于这个原因，考虑到乙醇衍生的 1,3-BD 可能含有难以去除的含氧污染物，本手稿首次研究了低浓度的一些含氧化合物（乙醛、巴豆醛、3 1,3-BD 单体中的-羟基丁醛、丙酮、水、乙醇、1,3-丁二醇、3-丁烯2-醇、巴豆醇和 1-丁醇) 可以影响使用叔碳酸钕催化剂进行的聚合反应并改变所得聚丁二烯产品的特性。
