The present invention generally relates to a process that prepares polyethylenes, poly-α-olefins or poly(co-ethylene-?-olefin) having backbone weight average molecular weights less than 2500 daltons. The process uses a metal-ligand complex as a precatalyst and can be carried out at temperatures ranging from 30° C. to 300° C. The relatively low molecular weight of the products enables improved viscosity control for a wide variety of applications.
本发明通常涉及一种制备分子量小于2500道尔顿的聚
乙烯、聚α-烯烃或聚(共
乙烯-α-烯烃)的过程。该过程使用
金属
配体复合物作为前催化剂,可在30℃至300℃的温度范围内进行。产品的相对较低分子量使得在广泛的应用中可以实现更好的黏度控制。
