    The invention relates to staking and copy-based propylene composition using calcium salts of phosphonic acids and esters for stabilization from exposure to light and temperature. A known polymer is "containing popropropyles and salts of phosphonic acid metals and their pp". ditch to stabilize it. However, the material being protected after the introduction of these compounds into it will in most cases acquire a solid color. Stronger than that, the stabilization effect is insufficient. The aim of the invention is to increase the stabilization effect and to obtain an uncolored composition. The goal is achieved by the fact that the polymer in the composition {content of polypropylene and aliphatic phosphonate, as the latter, contains a compound of the formula iL f -. (Hj-P-OB3j 0 "where R-, n Rj - C-Cd-alknl, R, - C-C g-alkyl, 1FI the following ratio of components, wt.%: Polypropylene 99.8-99.9 Aliphatic phosphonate 0.1-0.2 Compounds of the formula T are prepared, for example, by a known method til, according to which a reaction is carried out in water or in an aqueous-alcoholic mixture between a calcium salt and a phosphonic acid or its polyester. If free phosphonic acid is used as the starting compound or its polyester, then the suitable calcium salt is an oxide, an oxide hydrate or calcium carbonate. If the starting 1: 1m compound is used with Corresponding to the sodium salts of phosphonic acid or its polyester, then any calcium salts are chewed, have sufficient solubility in water or in mixtures with alcohols, such as ethanol, methanol, isopropanol or butanol, for example, chloride, pO1, nitrate, or calcium acetate. The compounds according to the invention are suitable as stabilizers of polypropylene, which can be in any form, for example in the form of a molding compound, insulation for cables. It is advisable to use calcium phosphonates, which have good antioxidant properties and are not susceptible to coating, as additives to fiber, polypropylene filaments or films, Calcium phosphonates show high activity and when polypropylene is added to copolymers Q / copolymerizable propylene, for example with oL-olefins, such as ethylene, 1-butene, 1-hex n or 1-octvn. The preferred content of propylene with more than 70%.
    Calcium phosphonates are introduced into the composition by conventional methods / for example, by dryly displacing the polymer with at least one calcium phosphonate in accordance with the invention and 20 subsequent processing in a mixer, on a mixing roll or extruder. These additives can also be applied to the polymer in the form of a solution or dispersion, after which jS it is necessary to evaporate the solvent,
    Calcium phosphoates can be used both in pure form and in admixture with other conventional additive ®. In the latter case, synergistic effects can be observed. As dfugih additives can be given, for example, the following substances:
    1. Phenolic antioxidants, such as npocTbte 2, b-; i-alkyl-forvols, for example 2, b-di-tert.-butyl-4-utilphenol, bisphenols, for example 1,1,3-tri- (5-tert-butyl-4-hydroxy-2-methylphenyl) -butane or 4 , 4-thiobic- (b-tetf. Butyl-3-methylphenop), hydroxybenzene derivatives of ars alactic com- pounds of 40 days, for example, 1,3,5-tri- (3,5-di-tert. -Butil-4- oCGibwnsyl) -2, 4, 6-methylbeneol, esters of p) - (3,5-di-tert.-butyl-4-hydroxyvinyl) -propionic acids and one- or 45 polyhydric alcohols, such as octadecanol, thiodiethylene glycol or pentaerythritol.
    2. Additives to prevent the polymer from disrupting the polymer field by UV radiation and light, such as 2 - (- phenyl) benzotriazole oxides, 2,4-bis (2-hydroxyphenyl) -6-alkyl-5- triazine, 2-hydroxybenzophenones, 1,3-bis-2- (2-.oxybenzoyl) benzenes, complex efcry of beisoic and substituted benzoic acids, acrylates, nickel compounds, sterically hindered amines or oxalic acid diamides.
    3. Metal deactivation, 40 such as H, m-bissalicyloyl hydrazine.
    4. Phosphites, such as tri- {ionylphenyl) phosphate; phyt or tri- {2, L-di-tert, -bu tylphenyl) -fos (1 "t.
    5. Compounds destroying re-5
    Kis, such as esters of R thiodipropionic acid.
    6. Other additives, such as softeners, emulsifiers, pigments, optical brighteners, flame retardant or antistatic agent.
    Example 1. Preparation of bis-fo-ethyl- (3,5-di-tert. -Butyl-4-oxybenzyl) - fo.sophatat a - calcium.
    328 g (1 mol) of O-ethyl-4-oxy-3, 5-di-tert.-butylbenzylphosphonic acid are suspended in 2.5 l of water and neutralized with 100 ml. 10 n. caustic soda solution (pH 6.5). As a result, a clear solution is formed, to which a solution of 123 g (0.525 mol) of calcium nitrate tetrahydrate in 130 ml of water is added dropwise at room temperature for 45 minutes. The па precipitating crystalline precipitate is filtered off with suction, washed with 500 ml of water and then dried for 14 hours at a temperature and pressure of 11 mm Hg. As a result, bis-fo-ethyl- (3,4-di-tert-butyl-4-hydroxybenzyl) phosphonate is obtained as a colorless crystal.

    The same compound can be obtained, suspending. 328 g (1 mol) of o-ethyl-4-oxyl-3, 5-di-tert-butylbasylphosphoric acid and 28 g (0.5 mol) calcium oxide in 6 liters of a 50% aqueous solution of ethyl alcohol and heating the mixture with reflux until a clear solution is formed. In order to divide the calcium salt formed above the indication, the solution is evaporated to approximately 1/6 of its original volume. In this case, VSH gradually forming a crystalline precipitate of the salt of Aysu III is described in the above way.
    Example 2. 1000 h. Non-stabilized psuyushka. polypropylene (ideks out-20) is mixed in a high-speed mixer with 1 part calcium stearate and 2.5 hours. chemical agents (rutile - Ti02, a also alternately with one of the additives listed in Table 01 below, after which the mixture is extruded at a temperature not exceeding 220 ° C and granulated. From the obtained granulate on a laboratory extrusion spinning machine, no higher than 280c spun a multifilament yarn, which is then stretched on a torsion bar in a thread with a final titer of 130/37 denier and a residual elongation of 30%. This multifilament yarn is wound in four layers in parallel rows on a cardboard to produce called mirror yarns and then measured th exponent discoloration by ASTM 1925-70 (smaller number corresponds good dye) 4 The results are shown in the table.
