    39, but it makes it possible to use lower concentrations of each of the salts than in the case of their separate change. The combination of salts improves the optical and physical properties of the polycarbonate obtained. Due to the use of smaller amounts of salt, a greater percentage of incident light is transmitted, the composition has less turbidity, which is natural for obtaining a crystalline transparent polycarbonate. The sheets obtained from the proposed composition have transparency, light transmission and low turbidity. In addition, the low concentration of salts retains the impact resistance of poly. carbonates. In addition, it was found that the addition of salts in the form of a solution results in a plaque-resistant polycarbonate composition with better optical properties than when the salt is added in ground form. If the refractive index is
    lagged additives are within the refractive index of the aromatic polycarbonate, i.e. t,) 65j then the polycarbonate composition and the molded products received from the bottom are transparent. This means that it is capable of transmitting light and is translucent or transparent. D Depending on how close the refractive index of additives and polycarbonate are, the compositions are transparent or translucent. If the additives in the applied concentration are partially or completely soluble in the polycarbonate resin, then the resulting products and compositions will be more transparent. Organic salts are preferred: sodium diphenyl fluoride 4-sulfonate; potassium diphenylsulfoxide-4-sulphonate; potassium diphenylsulfone-3-sulfonate; sodium diphenylsulfone-3-sulfonate; dipotassium diphenylsulfide-; disulfonate; dipotassium diphenylsulphon-; k disulfonate; 2,5-Dichlorobenzenesulfonate sodium; dipotassium diphenylsulfone-3.3 W disulfonate; polysodium polystyrene polysulfonate; poly-potassium poly-chlorostyrene) -polysulfonate. 8 Alkali and alkaline earth metal halides and their mixtures are used as inorganic halides;
    ba, facilitating demoulding, and other additives commonly used in transparent formulations. Polycarbonate resins. In addition, molded articles may have coatings, for example, resistant to scratching and backing.
    Example 1. 100 parts of an aromatic polycarbonate obtained by the reaction of 2, 2-bis - (, (- hydroxyphenyl; -propane) halides include sodium chloride, potassium iodide, potassium bromide, sodium bromide and potassium chloride. Aromatic polycarbonates are used as polycarbonates. with a refractive index of 1,, 65, obtained on the basis of diatomic phenols. The proposed composition is obtained by mixing an aromatic carbonate polymer with organic and inorganic salts. Organic and inorganic salts can be mixed with polycarbonate in finely divided form State or in the form of a solution. Preferably, organic and inorganic salts are dissolved in a solvent in which they are soluble, for example, in methanol or water. The mixture is mixed with polycarbonate salt in the form of an aqueous solution. The composition may also contain fillers, pigments, dyes, antioxidants , stabilizers, absorbers of ultraviolet rays, phosgene substances, in the presence of an acid acceptor and molecular weight regulator, with a viscosity of 0.57 are mixed with those given in table. 1 amounts of additives 13 laboratory mortar. Then the resulting mixture is fed into an extruder operating at, the resulting extrudate is crushed into tablets. Then from these tablets Jormat injection molding with rods. The properties of the products based on the obtained polycarbonate compositions are presented in table. 1. PRI mme R 2. The effect of the proposed additives in the form of fine powder and in the form of a concentrated aqueous solution. Upon receipt of the test samples 100 h, the polycarbonate obtained in example 1, is mixed with the specified in table. .2 amounts of additives. Samples that are tested for light transmission as in Example 1 are then molded. Samples are also tested for turbidity on a Gardner instrument, in which case 59063856
    A percentage of the total transmitted light, coy and inorganic salts improves the sub-flame diffused forward normal from the normal, and the angle of fire is more than 2 °, these results, based on the composition, are shown in Table. 2, the ability to use smaller concentrations. Thus, the use of additives in the preparation of
