    This invention relates to a composition} 1 comprising a polyvinyl chloride-compatible plasticizer, a flame retardant halide flame phosphate, which produces products such as flexible polyvinyl chloride films with high flame retardancy and low turbidity when this composition is introduced into the polyvinyl chloride composition.
    Compositions are known that contain a plasticizer compatible with polyvinyl chloride and a hapoidoalkyl phosphate flame retardant, for example, chlorinated or brominated gishkyl phosphate with 1 to 3 carbon atoms Y.
    However, these plasticizer compositions, with an increase in the ability of polyvinyl chloride compounds to retard the flame, increase the turbidity, forming a turbid product that has less transparency and less glare than is acceptable in some industrial applications.
    Closest to the proposed technical essence and the achieved result is a flame retardant composition comprising a dialkyl phthalate plasticizer and tris (dichloropropyl) phosphate C2.
    However, this composition also imparts turbidity to polyvinyl chloride compositions.
    The purpose of the invention is to reduce the turbidity of POLYVINYLHLOR1SCH SYN.
    formulations containing this composition.
    This goal is achieved by the fact that the flame retardant composition, including dial, ilftalatny plasticizer and tris (dichloropropyl) phosphate, additionally contains dimstilmetylphosphonate in the following ratio of components, dog, h:
    Dialkylft al ain

    The boiling point of dimethylmethyl phosphate (B2-63 C} is less than some of the treatment temperatures used to make polyvinyl chloride compounds at the same time does not evaporate to a significant extent (for example, according to the AZTMD 1203-6 IT method, the weight loss is less than 5%) from containing eio mixture when this mixture is included in the composition of the polyvinyl chloride composition to be processed.
    The proposed composition is intended to introduce vinyl chloride into polymers in order to produce flexible polyvinyl chloride films. Polyvinyl chloride material constituting the main part of the final product is known. Such materials include polymers formed not only by the polymerization of vinyl chloride monomer, resulting in the production of polyvinyl chloride homopolymer, but also by polymers formed by copolymerization of vinyl chloride monomer with other alpha. comic monomers with unsaturated ethylene bonds having a molecular weight of 260, which are copolymerized with vinyl chloride, to form polyvinyl chloride. Such comonomers include olefins (for example, ethylene, propylene, etc.), vinylidene monomers, for example, vinyl esters of monobasic organic acids containing 1-20 of carbon atoms (for example, vinyl ether, hexyl vinyl ether, benzyl vinyl ether, and so on. d.) and vinylidene chloride, alkyl acrylate esters, in which the alkyl group contains 1-20 carbon atoms (for example, methyl acrylate, butyl acrylate, octadecylacrylate, etc.) and the corresponding alkyl ether and dialkyl esters of dibasic x acids in which the alkyl group contains 2-8 carbon atoms (for example, dibutyl fumarate, diethyl maleate, etc.). Vinyl chloride polymers have a chlorine content of 45.0-56.7% and molecular weights such that the solution is eth; -: x polymers (with a concentration of 0.4 weight, in cyclohexanone at 25 ° C, has a viscosity of about 0, 3-0.6, a preferred viscosity limit of 0.4-0. A preferred class of vinyl chloride polymer is a polyvinyl chloride homopolymer, i.e., one that provides the most satisfactory properties of the final product, such as thermoplastics 1L | e sheets or film.
    The proposed composition is introduced into these polyvinyl chlorides in an amount of 10-70 parts by weight. per 100 parts of polyvinyl chloride polymer to obtain the desired polyvinyl chloride composition In addition to this composition, the polyvinyl chloride composition may contain, if necessary, such targeted additives as stabilizers, fillers, dyes, lubricants, co-softeners, etc. in accepted quantities. The other ingredient of the composition may be the second plasticizer (minor), for example, polyol esters such as pentaerythritol, sorbitol, mannitol, trimethylolpropane, etc., with monobasic acids containing 4-10 carbon atoms, such as acetic acid , oil and enantova, in an amount of about 5-15 wt.% from the main plasticizer. The weight ratio of the flame retardant to the primary plasticizer (and to the minor, if it is present in the composition) can vary within rather wide limits depending on the conditions in which the composition should be used, on the degree of plasticization and on the ability to slow down the flame, as well as on physical conditions. properties that it is desirable to impart to the final product. Typically, the phosphate flame retardant should be present in the composition in a slight excess. It is established that the most preferred weight ratio of phosphate to plasticizer is 5: 3. i The flame retardant plasticizing mixture proposed is obtained by simply mixing the various components of it to obtain a homogeneous liquid. PRI me R. 1. Two plasticizing mixtures are penetrated into flexible polyvinyl chloride films and using a turbidity meter (Hyunter’s differential color meter D25D-2), determine the haze value and light transmittance using the method ASTM D 1003-61. The main composition comprises 100 parts by weight. polyvinyl chloride homopolymer based resins (grade SCC-616). By weight flame retarding plasticizing mixture, 0.75 wt.h. barium-cadmium liquid stabilizer (brand Mark UL), and 0.5 weight, h. stearic acid as a lubricating agent. The control plasticizing mixture contains 50 ppm, tris (dichloropropyl) flame retardant (AyroB fi brand) FR -2, 20 wt.h. mixed plasticizer based on dialkyl (with a linear chain of C 6-10). phthalic acid ester and 10 parts by weight oily and enanthic acid pentaerythritol ester. The proposed mixture also contains 2Q weight.h. dimethylphosphonate. The turbidity index of the control mixture is 10.2%, while only 3.7% is proposed. This turbidity index is the percentage of light transmission that, when passing through the sample, deviates by more than 2.5 from the incident beam during light scattering.
