Abstract:The polar monomer is an olefin monomer with polar group. It includes polar monomer with halogen, polar monomer with oxygen atom, polar monomer with nitrogen atom, and polar monomer with phosphorus atom. The polar vinyl monomer is monomer with conjugated vinyl group and polar group. The polymerization of polar vinyl monomer produces a polymer with polar group. This polymer has obvious advantages over the traditional non-polar polyolefin materials in terms of viscosity, toughness, interfacial properties (dyeing and printing), and compatibility with solvents or other polymers. In order to obtain polymer with good physical properties, it is a hot spot to get a polymer with certain degree of regularity. The structure of the polymer has a significant impact on its physical properties, such as melting point, glass transition temperature and mechanical properties. The most effective way to obtain the stereoregular polymer is the development of the stereoselective catalysts for polar vinyl polymeization. This paper reviews the recent research progress in stereoselective catalysts for the polar vinyl monomer polymerization, the polar vinyl monomers involved include; methacrylate, methacrylamide, vinylphosphonate, vinyl pyridine, 2-isopropenyl-2-oxazoline and heteo-atom substituted styrene. The polymerization system includes the coordination polymerization, the Lewis pair, and the anionic polymerization system.
