- Polycarbonates can be produced using the so-called phase interface process.
- Dihydroxydiarylalkanes are in the form of their
- DE-A 4 129 545 describes a process for the preparation of suspensions of bisphenolates. These can be used in the phase interface process for the production of
- Polycarbonate can be used.
- Containers made of polycarbonate are used, for example, as water bottles. For aesthetic reasons, it is desirable to produce water bottles with a small yellowness index (YI) and high transmission. This is the object of the present invention.
- YI yellowness index
- the present invention thus relates to containers made of polycarbonate, the polycarbonate being produced by the interfacial process and the aqueous solution of an alkali salt of a bisphenol used here having a dissolved oxygen content of less than 150 ppb, preferably less than 100 ppb, particularly preferably less than 50 ppb.
- the polycarbonate according to the invention is produced in such a way that the others
- Raw materials apart from the aqueous solution of the alkali salt of bisphenol, contain no significant amount of oxygen. The rest of the production takes place in the absence of oxygen, as described for example in DE-A 4 227 272.
- the pumping loop and the tube reactors are flooded and the reaction vessel is blanketed with nitrogen, so that oxygen exclusion is ensured.
- the present invention furthermore relates to the production of the containers by the injection blow molding process or by the extrusion blow molding process.
- the injection blow molding process is a combination of injection molding and blow molding.
- the granules were melted and formed into a free-standing tube through a nozzle, which was then enclosed in a blow mold that squeezed the tube together at the lower end.
- the tube is inflated within the mold so that the tube is given the desired shape. After a cooling time, the mold is opened and the hollow body can be removed (cf.

- the bisphenol can be dissolved as a solid in the solution of an alkali hydroxide. However, it is preferred if, without having passed through the solid state, it is added directly to the solution of an alkali hydroxide as a melt at temperatures of 20 ° C. to 90 ° C., preferably 30 ° C. to 70 ° C.
- the almost oxygen-free aqueous solution of an alkali metal hydroxide used to prepare the aqueous solution of an alkali metal salt of a bisphenol can be obtained by
- Electrolysis can be produced. Storage and transportation of the solution of an alkali hydroxide after production should take place under inert gas.
- concentration of the alkali metal hydroxide solution obtained in the electrolysis is generally reduced by dilution with virtually oxygen-free, fully deionized water (demineralized water).
- the deionized water is produced in a manner known in principle, e.g. catalytically freed of oxygen by degassing or stripping with inert gas.
- the aqueous solution of an alkali metal salt of a bisphenol thus obtained has particularly low color numbers, which are of course also dependent on the
- Color number of the bisphenol used When using a bisphenol with a color number ⁇ 10 Hazen (ASTM D 1686), color numbers of ⁇ 1.5 Hazen, preferably ⁇ 1.0 Hazen can be achieved.

- Chain terminators can be used according to the invention.
- Phenols such as phenol, alkylphenols such as cresol and 4-tert-butylphenol, chlorophenol, bromophenol, cumylphenol or mixtures thereof are preferably used according to the invention as chain terminators.
- Chain terminators and branching agents can be added to the synthesis as a separate solution or else together with the bisphenolate. In the case of the solutions, care must be taken to ensure that they are the same according to the invention
- All of the starting materials and solvents used for the synthesis can be contaminated with corresponding impurities from their production and storage, the aim being to work with as clean starting materials as possible.
