Novel radiopaque heavy metal polymer complexes, compositions of matter and articles prepared therefrom |
摘要 |
Novel radiopaqaue materials comprise heavy metal salts, such as bismuth and uraniuim salts complexed with a polymer. The metallic complexes which are permanent, nonleachable and have radiopacities at least equivalent to that of aluminum do not adversely affect the mechanical and physical properties of compositions. They are useful as medical and dental resins, in fabricating medical and dental appliances, prosthetic devices, radiation shielding devices and radiopaque polyester fabrics for clothing.
