摘要

石脑油是原油蒸馏产品之一,与其他炼油产品(如液化石油气、汽油和柴油)相比,它给原油带来的附加值几乎是最低的。然而,石脑油可以转化为价值链末端的最高价值产品之一,即聚烯烃。虽然从原油中生产常规商品聚烯烃被认为是烯烃价值链中的最终产品之一,但也存在具有更高价值的特种聚烯烃。与传统的商品聚烯烃相比,特种聚烯烃是一种小体积、高性能的热塑性塑料,具有高利润率。近年来,一些特殊用途的功能化聚烯烃被开发出来,作为高性能工程热塑性塑料的高效取代剂。聚烯烃被开发为生产这些功能化热塑性塑料的经济高效的平台。它们是用高成本的原材料和复杂的生产工艺取代高性能聚合物的有希望的候选者。因此,功能性聚烯烃在高性能热塑性塑料的生产中引入了一个新的范例,扩展了烯烃的价值链并提高了盈利能力。高性能特种聚烯烃可能会在小众应用中找到特殊的市场。本章对工业特种聚烯烃和功能聚烯烃的现状和前景进行了综述。

Extending Alkenes’ Value Chain to Functionalized Polyolefins
Naphtha is one of the crude oil distillation products, bringing almost the lowest value-addition to crude oil, compared to other refinery products such as liquid petroleum gas, gasoline, and diesel. However, Naphtha can be converted to one of the highest value products at the end of the value chain, i.e., polyolefins. Although the production of conventional commodity polyolefins from crude oil, is considered as one of the final products in alkenes’ value chain, there are specialty polyolefins with higher values. Specialty polyolefins are small volume, high-performance thermoplastics with high-profit margins compared to traditional commodity polyolefins. Recently, some special purpose functionalized polyolefins have been developed as efficient substituents for high-performance engineering thermoplastics. Polyolefins are exploited as cost-effective platforms to produce these functionalized thermoplastics. They are promising candidates for replacing high-performance polymers with high-cost raw materials and elaborate production processes. So, functional polyolefins have introduced a new paradigm in the production of high-performance thermoplastics, extending the alkenes’ value chain and increasing profitability. High-performance specialty polyolefins may find exceptional markets in niche applications. In this chapter, the commercial specialty and functional polyolefins’ current situation and prospects are reviewed.
