Abstract
The invention relates to slabs consisting of polycarbonate. Said polycarbonate is produced according to the interface method and the aqueous solution of an alkaline salt of a bisphenol that is used, contains less than 150 ppb dissolved oxygen.
Description
The present invention relates to polycarbonate sheet, they are used to produce the purposes and the described glazing of glazing.
Polycarbonate sheet for example is used to produce glass port.In this case, wish that use has the high as far as possible transmittance and the sheet material of alap yellowness index.Though might reduce yellowness index by adding blue pigments, this is to be that cost obtains with the transmittance and the burnt hair look of sacrificing sheet material.In the weathering process of sheet material, importantly, the mechanical property of sheet material remains on the highest possible level, even like this at aging (Bewitterung) afterwards, sheet material also can keep high anti-mechanical influence (for example hail impact) property.
Polycarbonate can be produced by so-called phase interface method.In described method, mineral alkali such as sodium hydroxide solution and product polycarbonate be dissolved in easily wherein organic solvent in the presence of, dihydroxydiarylalkanes (being also referred to as bis-phenol) reacts in heterogeneous with their form and the phosgene of an alkali metal salt in the aqueous solution.
At Schnell, " Chemistry and Physics of Polycarbonates ", Polymer Reviews, Volume 9, Interscience Publishers, New York, London discloses the further details about the phase interface method of producing polycarbonate among the Sydney 1964.
The known polycarbonate sheet of prior art has shown following shortcoming: they can not fully satisfy above-mentioned requirement about high transmission rate, low yellowness index and the good maintenance of mechanical property when aging.
Therefore purpose of the present invention provides the polycarbonate sheet that does not show above-mentioned prior art shortcoming.
According to the present invention, this purpose reaches by polycarbonate sheet, wherein polycarbonate produce by the phase interface method and here the aqueous solution of an alkali metal salt of employed bis-phenol have the dissolved oxygen content that is lower than 150ppb.
The content of dissolved oxygen in the aqueous solution of bis-phenol an alkali metal salt is＜150ppb, and is preferred＜100ppb, especially preferred＜50ppb.
Therefore the present invention provides polycarbonate sheet, wherein polycarbonate produce by the phase interface method and here the aqueous solution of an alkali metal salt of employed bis-phenol have the dissolved oxygen content that is lower than 150ppb.
In addition, the present invention also provides glazing, for example is used for automobile or buildings, is particularly useful for the greenhouse, winter garden, motorbus shelter, billboard, sign board, protective shield, motor-vehicle glass window, window or roof.
Polycarbonate produced according to the invention makes other starting material except the aqueous solution of bis-phenol an alkali metal salt not contain the oxygen of the amount of can not ignore.In addition, as for example described in the DE-A 4 227 272, produce under the situation of getting rid of oxygen and carry out.
For example, in reaction vessel and tubular reactor configuration, pump circulation endless tube and tubular reactor are shrouded, with nitrogen with nitrogen wash and reaction vessel to guarantee to get rid of oxygen.
According to polycarbonate sheet of the present invention for example is solid sheet, the hollow sheet material (be also referred to as multi-layer sheet, or corrugated sheet, they are for example as glazing material.Described sheet material can be with the known mode of skilled person in this area in principle, for example by extruding or producing by injection moulding.
The following process of sheet material as thermoforming or surface modification, as applies the anti-scratch enamelled coating, and water-dispersible layer etc. also are feasible.This patent also relates to the moulded parts of being produced by these methods.
For producing the polycarbonate that sheet material according to the present invention is used, use dissolved oxygen content＜150ppb, preferably＜100ppb, the aqueous solution of an alkali metal salt of the bis-phenol of especially preferred＜50ppb, it can preferably have by making＜bis-phenol of 10ppb dissolved oxygen content with have＜alkali metal hydroxide aqueous solution of 100ppb dissolved oxygen content reacts under the situation of getting rid of oxygen and obtains.
Preferred an alkali metal salt is the sodium salt of bis-phenol.
Can bis-phenol used according to the invention be to react those that obtain by making ketone and aromatic hydroxy compound, this aromatic hydroxy compound be substituted and contain any secondary substituting group in contraposition, as cyano group, carboxyl, nitro or for example be phenol, neighbour and meta-cresol, 2,6-dimethyl phenol, o-tert-butyl phenol, 2-methyl-6-tert butyl phenol, neighbour-cyclohexyl phenol, O-SyL, o-isopropyl phenol, 2-methyl-6-cyclopentyl phenol, neighbour and m-Chlorophenol, 2,3,6-trimethylammonium phenol, preferred phenol, neighbour and meta-cresol, 2, the 6-dimethyl phenol, o-tert-butyl phenol and O-SyL.Phenol is particularly preferred.The carbonyl official can on have at least one aliphatic group ketone be preferred, acetone for example, methyl ethyl ketone, methyl propyl ketone, methyl isopropyl Ketone, metacetone, methyl phenyl ketone, pimelinketone, cyclopentanone, methyl-, dimethyl-and trimethylammonium-pimelinketone, they can also comprise together with the position methyl, for example 3,3-dimethyl-5-methylcyclohexanone (hydroxy isophorone (Hydroisophoron)).
Acetone, methyl phenyl ketone, pimelinketone and their homologous compound that carries methyl are more specifically preferred.Acetone is most preferred.By intensive inert nitrogen atmosphere is provided, guaranteed that the residual content of dissolved oxygen in bis-phenol is lower than 10ppb in the whole production method process.
