Abstract:
The present invention discloses a catalytic system for preparing highly branched alkane from olefin, which contains novel nickel or palladium complexes. In the presence of the catalytic system, highly branched oily alkane mixture can be efficiently obtained from olefins (such as ethylene) under mild conditions. The alkane mixture has a low bromine number, and can be used as a processing aid(s) and lubricant base oil with high-performance. Provides also was a method for preparing the catalyst and a method for preparing an oily olefin polymer.
