Definitions
- the present invention relates to compositions comprising a polymer selected from the group consisting of polycarbonate, a transparent polycarbonate-polyester blend, a copolyester carbonate and a transparent polyester and ester of branched alcohols and carboxylic acids, the carboxylic acids in turn carrying esterified OH functions, and Products made from these compositions, in particular plates.
- compositions containing polycarbonate are used in many fields.
- panels made from compositions containing polycarbonate are used, for example, for roofing or glazing.
- the compositions containing polycarbonate usually contain additional substances such as e.g. Lubricant (also called mold release agent).
- Lubricant also called mold release agent.
- Carboxylic acid esters for example, are used as lubricants.
- compositions containing polycarbonate and Guerbet alcohols are known.
- Guerbet alcohols are the products of the Guerbet reaction and can be produced, for example, by the Guerbet reaction.
- the Guerbet reaction is the self-condensation of alcohols under the influence of sodium or copper at approx. 200 ° C and elevated pressure.
- Polycarbonate sheets are known, for example, from EP A 0 110 221 and are provided for a large number of applications.
- the sheets are produced, for example, by extrusion of compositions containing polycarbonate. If necessary, coextrusion can be carried out with further compositions which contain polycarbonate and which additionally contain an increased proportion of UV absorbers.
- a recurring problem in the extrusion of such sheets is the settling of volatile constituents from the composition on the calibrator (in the case of multi-wall sheets) or on the rollers (in the case of solid sheets), which can lead to surface defects on the sheets.
- Volatile components are, for example, UV absorbers, mold release agents and other low molecular components of the composition.
- EP A 0 320 632 describes coextruded sheets from compositions which contain polycarbonate, which contain a UV absorber and can contain a lubricant.
- the disadvantage is that with a longer extrusion time, the surface of the plates by evaporation from the melt of the composition, especially in the
- the increased evaporation of the UV absorber from the melt of the composition leads to the formation of deposits on the calibrator or the rollers and finally to the formation of defects on the plate surface (e.g. white spots, waviness, etc.).

- WO 01/74935 teaches that mixtures of the esters of fatty acids and Guerbet alcohols and fatty acids and linear alcohols can improve the process for the production of plastic sheets by coxtrusion, in particular if the process is carried out over a long period of time (improvement of the long-term coextrusion behavior).
