摘　　要：乙丙橡胶钒系催化体系因其所制备产品序列分布均匀、结晶度低、组成分布较窄等优势,广泛应用于国内外乙丙橡胶生产企业。然而,钒系催化剂存在热稳定性差、活性中心寿命短、催化剂失活较快等问题,极大地降低了催化效率,提高了生产成本。为了实现降本增效,利用活化剂使得已经失活的钒系催化剂再活化,是工业上提高乙丙橡胶钒系催化剂活性的主要手段。本文综述了活化剂在国内外乙丙橡胶钒系催化体系应用方面的研究进展以及活化剂的加入对乙丙共聚反应活性以及所制备乙丙橡胶性能的影响,总结了活化剂在钒系催化体系中的活化机理。The vanadium catalytic system for ethylene-propylene rubber is widely used in domestic and international ethylene-propylene rubber production enterprises due to its advantages such as uniform product sequence distribution,low crystallinity,and narrow composition distribution.However,this catalytic system faces issues such as poor thermal stability,short active center lifespan,and rapid catalyst deactivation,greatly reducing catalytic efficiency and increasing production costs.To achieve cost reduction and efficiency improvement,the use of activators to reactivate deactivated vanadium catalytic systems is the main method for improving the activity of ethylene-propylene rubber vanadium catalytic systems in industrial applications.This article provides an overview of the activators research progress based on the Ziegler-Natta vanadium catalytic systems of ethylene-propylene copolymerization.The article demonstrated the activator effect on the reactivity of ethylene-propylene copolymerization and the properties of the as-synthesized ethylene-propylene rubber.It also summarized the possible activation mechanism of the activators in vanadium-based catalytic systems.
