Abstract

Disclosed is a new polyolefin catalyst and preparation therefor. Specifically, disclosed is a catalytic system comprising a new complex of iron, cobalt, nickel, palladium, and platinum. In the presence of the catalytic system, oily polyethylene can be efficiently obtained from simple olefins such as ethylene under mild conditions, highly branched oily alkane mixture is then obtained after hydrogenation. The alkane mixture can be used as a processing aid and a high-performance lubricant base oil. The present invention also provides a method for preparing the catalyst, a method for preparing the highly branched oily alkane mixture and a method for preparing functional polyolefin oil.
