During olefin polymerization process, a rapid and reversible chain transfer reaction between the metal complexes is of great importance. This reaction not only affects the activity of the catalytic system and the molecular weight of the polymer but also provides the metal complex with long alkyl chain, which can be used in the preparation of some high quality polyolefins, such as functionalized polyolefins and olefin multiblock copolymers. This review describes the major advances in this field.

Key words: olefin polymerization, chain transfer, metal complex
