Definitions

• the invention was based on the object of providing water-spreading plastic bodies which can be produced in a particularly simple manner.
• substrates which can be obtained by extrusion, injection molding and by casting processes should be able to be used for the production of the plastic bodies.
• claim 20 provides a solution to the underlying problem.
• the cycloolefinic polymers can be polymerized in a solvent, for example, using aluminum compounds, vanadium compounds, tungsten compounds or boron compounds as a catalyst.
• Phenyl (meth) acrylate where the aryl radicals can in each case be unsubstituted or substituted up to four times;
• these comonomers are used in an amount of 0 to 60% by weight, preferably 0 to 40% by weight and particularly preferably 0 to 20% by weight, based on the weight of the monomers, the compounds being used individually or can be used as a mixture.
• Preferred plastic substrates which have been produced by the casting chamber process can be obtained commercially from Röhm GmbH & Co. KG under the trade name ⁇ Plexiglas GS.
• Characteristics are based on polymers which have polar groups and are located in the adhesion-promoting layer, the polymers showing low solubility and low swellability in water. In general, the solubility of the polymers of the intermediate layer is less than 1 g / l.
• These compounds include tetraalkoxysilanes, for example tetramethoxysilane, tetraethoxysilane; Trialkoxysilanes, for example methyl-trimethoxysilane, methyl-triethoxysilane, ethyl-trimethoxysilane, n-propyl-trimethoxysilane, n-propyl-triethoxysilane, i-propyl-triethoxysilane; Dialkoxysilanes, for example dimethyldimethoxysilane, dimethyl-diethoxysilane, diethyl-dimethoxysilane, diethyl-diethoxysilane, di-n-propyl-dimethoxysilane, di-n-propyldiethoxysilane, di-i-propyl-dimethoxysilane, di-i-propylane diet.
• Trialkoxysilanes for example methyl
• the flood coating processes are known to the person skilled in the art. Generally, a liquid is poured over the material. The pressure is generally so low that the liquid hitting the substrate is none Droplet generated. Excess coating agent is collected in a tub and, if necessary, applied again using a filter. In general, the application takes place via nozzles, but the pressure is chosen to be relatively low. These nozzles are guided over the plate or along the edge of the plate via mechanical devices, so that the liquid applied with very low pressure creates a flood curtain that evenly coats the substrate. The amount of liquid and the feed with which the jet is guided over the substrate are selected so that the coating is applied evenly. More detailed information on this can be found in Brock / Groteklaes / Mischke "Textbook of coating technology", 2nd edition, 1998, Vincentz Verlag.
• the layer thickness of the intermediate layer is not particularly critical, although the sum of the layer thicknesses of the inorganic coating (a) and the intermediate layer (b) may not exceed 700 nm. For economic reasons, however, this is chosen to be relatively low if possible, the lower limit resulting from the stability of the entire coating (a) and (b). In general, however, the thickness of the adhesion-promoting intermediate layer after curing is in a range from 50 nm to 400 nm, preferably 100 nm to 200 nm, without any intention that this should impose a restriction.
• the layer thicknesses of the coatings (a) and / or (b) can be determined by recording a transmission electron microscope (TEM), the mean value being generally determined via the integral of the layer surface.
• TEM transmission electron microscope
• the preferred cycloalkyl groups include the cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl and the cyclooctyl group, which are optionally substituted with branched or unbranched alkyl groups.
• the preferred alkoxy groups include the methoxy, ethoxy, propoxy, butoxy, tert-butoxy, hexyloxy, 2-methylhexyloxy, decyloxy or dodecyloxy group.
• the radical R 1 very particularly preferably represents a methyl or ethyl group.
• the previously described coating compositions can be obtained commercially under the trade name ⁇ Ludox (Grace, Worms); ⁇ Levasil (Bayer, Leverkusen); ® Klebosol, (Clariant) can be obtained.
