Abstract
X-ray detectable molded articles prepared from polycarbonate resins are disclosed. The articles, preferably toys or medical equipment, are molded of polycarbonate the structure of which contains units derived from iodophenyl.
Claims5
An X-ray detectable article molded from a thermoplastic composition comprising polycarbonate having in its molecular structure at least one unit derived from iodophenyl carbonate, said polycarbonate prepared from diphenols conforming to HO—Z—OH wherein Z denotes a divalent aromatic radical having 6 to 30 carbon atoms.
An x-ray detectable toy molded from a thermoplastic composition comprising polycarbonate having in its molecular structure at least one unit derived from iodophenyl carbonate, said polycarbonate prepared from diphenols conforming to HO—Z—OH wherein Z denotes a divalent aromatic radical having 6 to 30 carbon atoms.
An x-ray detectable medical equipment molded from a thermoplastic composition comprising polycarbonate having in its molecular structure at least one unit derived from iodophenyl carbonate, said polycarbonate prepared from diphenols conforming to HO—Z—OH wherein Z denotes a divalent aromatic radical having 6 to 30 carbon atoms.
A method of imparting of x-ray detectability to an article molded from a thermoplastic composition comprising using at least some polycarbonate resin having in its molecular structure at least one unit derived from iodophenyl carbonate, said polycarbonate prepared from diphenols conforming to HO—Z—OH wherein z denotes a divalent aromatic radical having 6 to 30 carbon atoms.
