Claims
- 1. A method for taking a radiograph, comprising administering to a subject an iodine-substituted aromatic polymer having an iodine content of 1 to 75% by weight as a radiographic contrast medium, wherein said aromatic polymer in said iodine-substituted aromatic polymer is an aromatic linear polymer obtained from one or more aromatic monovinyl monomers selected from the group consisting of styrene, vinyltoluene and vinylnaphthalene.
- 2. A method for taking a radiograph, comprising administering to a subject an iodine-substituted aromatic polymer having an iodine content of 1 to 75% by weight as a radiographic contrast medium, wherein said aromatic polymer in said iodine-substituted aromatic polymer is an aromatic cross-linked polymer obtained from a combination of one or more aromatic monovinyl monomers selected from the group consisting of styrene, vinyltoluene and vinylnaphthalene and one or more cross-linking agents which are bifunctional or more highly functional vinyl monomers selected from the group consisting of divinylbenzene, trivinylbenzene, divinyltoluene, divinyldiphenyl ether, ethylene glycol dimethacrylate, trimethylolpropane trimethacrylate, divinylpyridine and trivinylpyridine.
- 3. A method for taking a radiograph, comprising administering to a subject an iodine-substituted aromatic polymer having an iodine content of 1 to 75% by weight as a radiographic contrast medium, wherein said aromatic polymer in said iodine-substituted aromatic polymer is an aromatic cross-linked polymer obtained from a combination of styrene as an aromatic monovinyl monomer and divinylbenzene as a cross-linking agent.
- 4. A method for taking a radiograph, comprising administering to a subject an iodine-substituted aromatic polymer having an iodine content of 1 to 75% by weight as a radiographic contrast medium, wherein said aromatic polymer in said iodine-substituted aromatic polymer is an aromatic cross-linked polymer obtained from a combination of one or more aromatic monovinyl monomers selected from the group consisting of styrene, vinyltoluene and vinylnaphthalene and one or more other monomers selected form the group consisting of acrylonitrile, methyl methacrylate, octadiene and isoprene.
- 5. A method for taking a radiograph, comprising administering to a subject an iodine-substituted aromatic polymer having an iodine content of 1 to 75% by weight as a radiographic contrast medium, wherein said aromatic polymer in said iodine-substituted aromatic polymer is an aromatic cross-linked polymer obtained from a combination of polyvinyl alcohol, styrene and divinylbenzene.
- 6. A method for taking a radiograph, comprising administering to a subject an iodine-substituted aromatic polymer having an iodine content of 1 to 75% by weight as a radiographic contrast medium, wherein said aromatic polymer in said iodine-substituted aromatic polymer is polystyrene.
