Definitions

  • the invention relates to transparent polycarbonate molding compositions for plastic articles which contain at least one thermal stabilizer and a mold release agent and which have a lower tendency to accumulate dust.
  • a known method to reduce dust accumulation on plastic bodies is through the use of antistatic agents.
  • Antistatic agents are described in the literature for thermoplastics (see e.g. Gumbleter, Müller, Plastic Additives, Hanser Verlag, Kunststoff, 1996, p. 749 ff), which restrict dust accumulation. These antistatic agents improve the electrical conductivity of the plastic molding compounds and thus dissipate surface charges that form during manufacture and use. As a result, dust particles are no longer attracted and consequently there is less dust accumulation.
  • Antistatic is applied to the molded plastic body after processing, an internal antistatic is added as an additive during processing.
  • an internal antistatic agent is usually desirable, since no further steps are necessary to apply the antistatic agent after processing. So far, however, no internal antistatic has been known for transparent settings of polycarbonate, which effectively limits the accumulation of dust and at the same time does not impair the advantageous properties of this material such as high transparency, low haze and high impact strength.
  • a disadvantage of adding antistatic agents is that, like any additive added, they increase the production cost of an article. Therefore, it would generally be desirable to use as few additives (number and amount) as possible.
  • thermoplastic molding composition which, as an amorphous thermoplastic polymer, contains polycarbonate and at least one antioxidant and a mold release agent, the antioxidant comprising at least one stabilizer from the group TPP, tetrakis (2,4-di-tert-butylphenyl) -4,4'-biphenylene-diphosphonite, Irganox 1222, octadecyl-3- (3 ', 5 ' -di-tert-butyl-4'-hydroxyphenyl) propionate, Irganox ® HP2921, Anox ® TB331, TB123 Anox ® or a mixture thereof, preferably in amounts 0001-1 wt .-%, more preferably is between 0.01 and 0.1 wt .-% contains
