Definitions

  • the present invention relates to the use of iodophenyl carbonate-containing polycarbonates for the production of special moldings.
  • iodophenyl carbonate-containing polycarbonates are:
  • Special molded parts in the sense of the present invention are in particular those for medical applications, such as probes or joint parts, and toys for children, such as building blocks.
  • Polycarbonates are unsuitable for this purpose because their contrast in the X-ray image increases is low.
  • a material that is used for this purpose is, for example, PVC, whose plasticizer content is undesirable in the medical field and whose mechanical properties do not meet the requirements.
  • Known iodine-containing polymers also have insufficient mechanical properties and are difficult to produce.
  • the task was therefore to develop molding compositions which, with good mechanical properties and high transparency and a glass temperature well above 100 ° C., have a good contrast in X-ray examinations.
  • the great advantage of the molded parts according to the invention is that they have an improved X-ray contrast and are therefore easily recognizable, that is to say they can be used well on the one hand in targeted operations, and on the other hand to correct accidents which arise from swallowing toys in children.
  • Dipodyl carbonates containing iodine and their addition to polycarbonates are known from US Pat. No. 3,382,207.
  • iodine-containing phenols are known as chain terminators for polycarbonates. See also the corresponding GB-PA 1 1 63 816.
  • iodine-containing compounds are known as additives to polycarbonates (column 4, line 64; column 5, line 43).
  • Polycarbonates according to 1) with M w between 3000 and 40,000 and with iodophenyl carbonate end groups are preferably those which have end groups of the formula (I)
  • R j to R 3 are H, Ci-C ⁇ optionally branched alkyl, Cl, Br or J, with the proviso that at least one of the radicals RR 2 and R 3 is J.
  • Preferred end groups are 4-iodophenyl carbonate and 2,4,6-triiodophenyl carbonate
  • Suitable diphenols for the preparation of the polycarbonates according to 1) are those of the formula (II)
  • Z stands for a divalent aromatic radical with 6 to 30 carbon atoms.
  • Preferred diphenols are l, l-bis (4-hydroxyphenyl-1-phenylethane, l, l-bis (4-hydroxyphenyl) cyclohexane, 2,2-bis (4-hydroxyphenyl) propane and l, l-bis - (4-hydroxyphenyl) -3, 3,5-trimethylcyclohexane.
  • polycarbonates according to 1) are either known or can be prepared by processes known from the literature, see for example the prior art cited above.
  • Preferred diphenol-bis-iodophenyl carbonates according to 2) are those of the formula (III)
  • Ri, R 2 , R 3 and Z have the meaning given for formulas (I) and (II).
  • Preferred bisiodophenyl carbonates according to 3) are those of the formula (IV)
  • R j , R 2 , R 3 and Z have the meaning given for formula (I).
  • the diphenol-bis-iodophenyl carbonates according to 2) and the iodophenyl carbonates according to 3) are either known from the literature or can be prepared by processes known from the literature.
  • the iodophenyl carbonate-containing polycarbonates to be used according to the invention in accordance with variants 1), 2), 3) or 4) are said to have iodine concentrations between 0.1% by weight. and 20% by weight, preferably between 1% by weight and 15% by weight, in particular between 3% by weight and 10% by weight, based in each case on the total weight of variants 1), 2), 3) or 4)
  • iodophenols are compounds available in the chemical trade or may be accessible in organic syntheses from aromatic intermediates via the detour via diazonium salts. They can be used individually, in combinations, possibly also in combinations with customary chain terminators such as phenol, p-tert-butylphenol, hexylphenol, i-octylphenol or nonylphenol
  • Suitable branching agents are triphenols, trimesic acid (trichloride), cyanuric acid trichloride and 3,3-bis (3-methyl-4-hydroxyphenyl) -2-oxo-2,3-dihydroindole
  • Both the iodophenyl-containing polycarbonates according to 1) and the conventional polycarbonates used as mixing partners according to 2), 3) and 4) can be used with the for Polycarbonates usual additives such as thermal stabilizers, mold release agents, stabilizers against ⁇ and ß radiation, and antistatic agents.
  • ⁇ re ⁇ is measured in dichloromethane at 25 ° C. and a concentration of 0.5% by weight.
  • the iodophenyl carbonate-containing polycarbonates obtained according to Examples 1 to 4 are molded into building blocks on an injection molding machine.
  • the x-ray contrast of these molded parts is so great that they can be discovered in the stomach of children.
