Definitions
- the invention relates to a polyester molding composition which gives moldings with good mold release and metallizability.
- WO 02/92688 describes the addition of a polysiloxane for this purpose.
- a polysiloxane for this purpose.
- Similar systems are described in JP-A 11061382 and JP-A 11241006;
- a modified silicone oil is added to a blend of polyester and polycarbonate, the functional groups such.
- B. contains epoxy groups, with which a connection to the polymer matrix is intended.
- Experience has shown that such a reaction with the few polyester end groups, however, always incomplete instead, so that there are significant concentrations of low molecular weight compounds that lead to outgassing at high service temperatures with the disadvantages described above.
- the object of the present invention was to develop a directly metallizable polyester molding composition with good adhesion of the metallization on the molding, wherein the mold release and the surface quality of the metallization should be optimized. This should be achieved while avoiding deposits in the injection mold.
- the Aufgäbe is solved by the use of a molding composition for the production of metallizable moldings containing the following components:
- thermoplastic polyester I. 50 to 99.98 parts by weight, preferably 80 to 99.9 parts by weight and more preferably 90 to 99.8 parts by weight of thermoplastic polyester,
- IL 0.02 to 5 parts by weight, preferably 0.1 to 3 parts by weight and more preferably 0.2 to 2.5 parts by weight of a copolymer containing Polysiloxariblöcke and polyester blocks, preferably Polysiloxanblöcke and Polylactonblöcke,
- Pigments, antistatic agents, reinforcing agents and stabilizers the sum of all parts by weight being 100.
- Thermoplastic polyesters are prepared by polycondensation of diols with dicarboxylic acids or their polyester-forming derivatives such as dimethyl esters.
- Suitable diols have the formula HO-R-OH, where R is a divalent, branched or unbranched aliphatic and / or cycloaliphatic radical having 2 to 40, preferably 2 to 12 represents C atoms.

- the molding material is prepared from the individual components by conventional methods, usually by melt blending in a kneading aggregate. It can be processed into shaped parts using conventional techniques such as injection molding or extrusion. These moldings can be directly metallized by all known methods, both wet-chemically and by vacuum deposition, for example by vapor deposition, sputtering or plasma CVD processes. Eventually, prior to metallization, the polymer surface is pretreated by techniques known to those skilled in the art, such as vacuum gating. In general, chromium, nickel or, in particular, aluminum are applied as the metal, and so-called precious metals, such as, for example, palladium, are also applied. The metal layer thus obtained can then be provided with an additional layer to increase the scratch resistance, such as by painting or vacuum deposition methods that make use of, for example, silicon-containing compounds.
