Abstract

The limited supply of natural rubber and the high demand for rubber have promoted the development of synthetic rubber. Metal-catalyzed coordination polymerisation is the main route for the synthesis of highly regular rubber materials today. Transition metal iron catalysts are of great importance in the preparation of synthetic rubbers due to their abundance

low price

low toxicity

high activity and high selectivity. This work summarizes the recent progress of Ziegler-Natta ternary iron catalysts

-bidentate ligand and

-tridentate ligand supported iron catalysts in 1

3-diene monomer polymerization. The relationship between catalytic performance such as polymerization activity

selectivity

polymer molecular weight and its molecular weight distribution

and other factors such as catalyst composition

structure and polymerization conditions are illustrated. This review could provide references and ideas for the design and synthesis of high-performance 1

3-diene polymerization iron catalysts.
