Claim Text:
1. A method for producing a polymer light-emitting material for an organic electroluminescent device which comprises: mixing a thermoplastic resin having a weight average molecular weight of 2,000-1,000,000 and containing a reactive functional group in a unit constituting the backbone and a metal-containing phosphorescent dopant compound comprising an organic metal complex containing at least one metal selected from ruthenium, rhodium, palladium, silver, rhenium, osmium, iridium, platinum, and gold and containing a reactive group capable of reacting with the said functional group to form a linkage and allowing the said functional group to react with the said reactive group so as to link a phosphorescent dopant moiety derived from the metal-containing phosphorescent dopant compound to the unit constituting the backbone of the thermoplastic resin; wherein the content of the metal in the said polymer light-emitting material is 0.001-20 wt %; and wherein the thermoplastic resin is a polyhaloalkylaromatic vinyl resin and the reactive functional group is a haloalkyl group.
