4-Methyl-1-pentene(4M1P)

which main purpose is to prepare homopolymers and copolymers

is an important branched chain α-olefin. Although majority 4M1P copolymers have not to be industrialized

the copolymers with excellent mechanical and optical properties have became a hot research topic on the field of foreign polyolefins as a new type synthetic resin. In this paper

the research and development status of copolymerization catalysts including Ziegler-Natta catalysts

metallocene catalysts and transition metal catalyst for copolymerization of 4M1P and olefin has been reviewed. The influence of catalyst structure on the molecular structure of the copolymers was summarized emphatically. And the α-Diimine Nickel Catalyst catalytic mechanism of typical 4M1P copolymerization was also briefly introduced

as well as prospects for further work in this field. This paper provided theoretical support for developing of high-end polyolefin new material.
