Abstract

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.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 96 words
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.
Claim 2
Dependent Claim 96 words
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.
Claim 3
Dependent Claim 44 words
Polymerization catalyst according to claim 1 wherein the functional group to which the metal component is bound is hydroxyl, amino, imino carboxyl, mercapto alkyl phosphine and/or aryl phosphine or wherein the metal, metal ion or metal complex forms a π-complex with the base polymer.
Claim 4
Dependent Claim 19 words
Polymerization catalyst according to claim 1 wherein the metal component is also bound to low molecular ligands or anions.
Claim 5
Dependent Claim 33 words
Polymerization catalyst according to claim 3 wherein the ligand is carbonmonoxide, a phosphine, halogen, halogenide, cyanide, olefine, aromatic, cyclopentadienyl or donor molecule of the fifth or sixth main groups of the periodic table.
Claim 6
Dependent Claim 25 words
Polymerization catalyst according to claim 1 wherein the metal or component is bound to a hydroxyl group-containing basic polymer forming an alcoholate or alkoxy complex.
Claim 7
Dependent Claim 28 words
Polymerization catalyst according to claim 5 wherein the hydroxyl group-containing organic basic polymer is a polyethylene glycol, monoalkoxy-polyethylene glycol, monophenoxy polyethylene glycol, polyvinyl alcohol or hydroxy methylated polystyrene.
Claim 8
Dependent Claim 43 words
Method of producing the polymeric catalyst of claim 1, which comprises reacting a functional group-containing organic polymer with a metal salt or metal complex of the metal component whereby the corresponding metal becomes bound to the polymer by exchange of low molecular ligands.
Claim 9
Dependent Claim 18 words
Method according to claim 7 wherein the functional group-containing organic polymer is an organic polymer containing hydroxyl groups.
