Developing low-molecular-weight dendritic polyethylenes as new molecularly-engineered synthetic lubricant base stock

由于现代汽车和机器需要更省油、更轻、更小、寿命更长的发动机，因此发动机润滑油必须满足日益严格的要求，以满足高要求，并提供切实的性能和经济效益。 与基于来自石油的矿物基础油的常规润滑剂相比，由具有均匀和明确分子结构的合成基础油配制的合成润滑剂已经显示出突出的性能优势，所述常规润滑剂具有不期望的复杂组成和广泛分布的性能特性。由于来自其他基础油的激烈竞争以及市场对润滑油性能的日益增长的需求，合成润滑油行业被迫开发和销售下一代高性能合成基础油技术，以保持在全球市场上的竞争力。

Owing to the drive for more fuel-efficient, lighter, and smaller engines with longer lifetime for modern automobiles and machines that can operate in extreme conditions, engine lubricants have to meet increasingly stringent requirements to match the high demands and to offer tangible performance and economic benefits. Synthetic lubricants, formulated from synthetic base stocks of uniform and well-defined molecular structures, have shown outstanding performance advantages compared to conventional lubricants based on mineral base oils from petroleum, which have undesired complex compositions and broad distributed performance properties. Owing to the severe competition from other base stocks and increasing market demands on lubricant performance, the synthetic lubricant industry is driven to develop and market next-generation, high-performance synthetic base stock technologies to remain competitive in the global market.
