Aqueous Catalytic Polymerization of Olefins

摘要: Catalytic conversions in aqueous environments by transition metal complexes have become a well-established field over the past two decades. However, vast majority of investigations focussed on small-molecule synthesis. This may appear somewhat surprising as water is particularly attractive reaction medium, especially for polymerization reactions. For example, emulsion and suspension carried out today large scale noncatalytic free-radical routes. Polymer latices can be obtained product, that is, stable dispersions polymer particles size range 50 to 1000 nm. Such possess unique property profile. Amongst other advantages, use dispersing medium environmentally friendly. In comparison these reactions, catalytic polymerizations olefinic monomers received less attention. considerable advances an increased awareness this emerged during few years. A variety high molecular weight polymers ranging from amorphous or semicrystalline polyolefins polar-substituted hydrophilic materials now been prepared water. based number readily available are accessible activities 10 5 turnovers per hour already reported. As another investigated protein inhibitors. versatile spanning colloids, polymer, coordination chemistry has emerged.
