【摘要】 合成聚异戊二烯化学组成与天然橡胶相同,通常用于生产轮胎、橡胶工业制品、输送带、衬垫、V带、胶板、医药用制品、密封件、胶鞋及体育运动用制品等领域。合成聚异戊二烯是重要的合成橡胶材料,而采用不同催化体系、不同聚合方法可得三种立体结构及物理机械性能截然不同的同分异构体（1,2结构尚未制得）。本文对聚异戊二烯国内外研究现状及应用前景进行了分析,着重介绍了顺式-1,4-聚异戊二烯、反式-1,4-聚异戊二烯,3,4-聚异戊二烯的结构和性能特性,总结了不同催化剂体系、不同聚合方法下合成聚异戊二烯结构特点。同时介绍了一些国内外异戊二烯的生产方法以及用途,对我国异戊二烯的开发利用提出建议,从异戊烷脱氢法、化学合成法、裂解C₅馏分萃取蒸馏、生物发酵法等方面介绍异戊二烯的制备方法,重点介绍了新型生物发酵法制备异戊二烯的制备方法。更多还原

【Abstract】 Synthetic polyisoprene is a kind of important synthetic rubber material, and using different catalytic systems, different polymerization methods can get three kinds of isomeric compounds with different spatial structures and physical and mechanical properties(1,2 structure has not yet been prepared).In this paper,we systemically introduce the production technology and catalytic system as well as the production capacity of polyisoprene,and emphatically introduce the structures and performance characteristics of cis-1,4-polyisoprene, trans-1,4-polyisoprene, 3,4-polyisoprene. This paper introduces some methods of production and application of isoprene, and puts forward some suggestions on the development and utilization of the Chinese.Describes several dominating production technologies such as dehydrogenation of isopentane, chemical synthesis, biochemical fermentation,cracked C5 extraction and distillation.更多还原
