Abstract
Soluble catalysts for polymerizations are provided which are formed from an organic polymeric material containing at least one functional group bound to a metal, metal ion or metal complex. These catalysts can be used to promote all types of polymerizations, such as of vinyl compounds, etc. These catalysts are produced by reacting the basic polymer with a metal salt or metal complex, particularly of a metal of the third through the eighth subgroups of the periodic table or of the third and fourth main groups of the periodic table, the catalyst being formed by exchange with the metal or metal ion being bound to the polymer.
Claims8
As a soluble catalyst for polymerization reactions, an organic polymer having at least one functional group bound to a metal component and having a molecular weight of 1000-10,000,000, wherein the organic polymer is a polystyrene, polyvinyl alcohol, polyvinyl ether, polyvinyl amine, polyacrylic acid, polymethacrylic acid, polyvinyl pyrrolidone, polyethylene glycol, polypropylene glycol, polyethylene imine, polyurethane, polyester or mixed polymerisate of mixed condensate of the corresponding monomer, and wherein the metal component is at least one of the metals selected from the group consisting of Ti, U, V, Zr, Co, Ni, Cr, Mo, W, Al, Zn and Fe.
