Claim:
A polymer-supported metal complex catalyst represented by the following chemical formula 1 wherein M 1 and M 2 , which may be identical to or different from the others, are selected from a group consisting of rhodium, palladium, ruthenium, rhenium, iron, nickel, copper, platinum, bismuth, cobalt, chromium, molybdenum, and tungsten; X is an oxygen atom; R 4 is an alkyl group, an aryl group, an aralkyl group, an alkyloxy group or an alkylamino group, which may have substituents; k is 1 to 15% and m is more than 0 and equal to or less than 99% based on k+l+m and l is the remainder; and n is an integer between 2 and 4, which is determined by the valences of M 1 and M 2 ; and R 1 to R 3 are defined below, wherein the polymer-supported metal complex catalyst is prepared by a method comprising the steps of: (1) performing a ligand exchange reaction between a coordinating compound and a complex, wherein the coordinating compound is represented by the chemical formula 21: wherein R 10 is a divalent hydrocarbon group, which may contain heteroatoms; and X is defined as above, and the complex is represented by the following chemical formula 5 so that metals (M 1 and M 2 ) are supported by the coordinating monomer, (R 4 CXO) n M 1 M 2 , [chemical formula 5] wherein R 4 , X, n, M 1 and M 2 are defined as above; (2) separating a compound represented by the following chemical formula 22 from the coordinating compound with supporting metals (M 1 and M 2 ), wherein R 10 , R 4 , X, n, M 1 and M 2 are defined as above; (3) preparing (a) a coordinating monomer represented by the following chemical formula 23 by introducing a vinyl group to the coordinating compound wherein R 1 is a divalent hydrocarbon group, which may contain heteroatoms, and R 4 , X, n, M 1 and M 2 are defined as above; and (4) copolymerizing (a) the coordinating monomer with supporting metals (M 1 and M 2 ), (b) a hydrophobic monomer represented by the chemical formula 3, wherein R 2 is an aromatic group and other carbons in the vinyl group may have substituents, and (c) a polymeric monomer represented by the chemical formula 4 wherein R 3 is a divalent hydrocarbon group represented by the chemical formula wherein R 6 and R 7 are independently —O—, —S—, —NR 8 — or PR 9 —, wherein R 8 and R 9 are independently a hydrogen atom, an alkyl group or an aryl group; o is an integer between 0 and 4; p is an integer between 1 and 12; q is an integer between 0 and 4; and r is 1 or 2.
