    Compound B R tCH3 3f - R -H, R2 -CH, N (R Compound C o R Compound DRH; R - :: H2N (R with R -CH2CH20H) Samples are obtained from the composition and tested for self-extinguishing. The average burning time is , s: Without an additive With compound A 1.60 With compound B 1.02 With compound C 0.51 With compound D 0.53 EXAMPLE 2 Preparing several mixtures containing 100 parts by weight of crystalline polystyrene 0.05 parts by weight of BHT, 0.035 parts by weight of zinc stearate and 0.75 parts by weight of flame retardant. Some mixtures are also added with 0.20 parts by weight of benotriazole. Samples are prepared from the composition and tested for self-extinguishing Table 1 shows the dependence of the self-extinguishing time qT of the used flame retardant Table The average time of burning is ANTIPYRENE, with benzot without triazole benzoazole Tetrabromide-acetylene 8,21 Dibromotetrachloroethane 15,75 Tetrachloroethane 60, 0 Example 3. A mixture is prepared, holding 100 wt.h. crystalline polystyrene, 0.05 parts by weight of BHT, 0.035 parts by weight of zinc stearate, 3.75 May, including pentabrommonochlorocyclohexane and 1.75 parts by weight benzotriaeol Samples are prepared from the composition and tested for self-extinguishing. . The average burning time is 0.42 s. EXAMPLE 4 Preparing formulations based on 100 wt.h. polystyrene with enhanced impact strength (with uchuch); 10 wt.h. flame retardant and 5. wt.h. antimony trioxide. To a portion of these formulations, 2 mab isotriazole is also added. Samples are prepared from the composition and tested for self-extinguishing. PRI me R 5. A plate is molded on the basis of expandable polystyrene beads. la, containing pentane as a substance that promotes swelling. In the experiment, 1.5 wt.h. pentabromyl and cyclohexane and 0.2 wt.h. benzotriazole compounds corresponding to formula I / where R is H, R (R), where R. Samples are prepared from the composition and tested for self-extinguishing. The average burning time is 8., O c. In another experiment without a benzotriazole compound, the average burning time is 17.0 seconds. Example b ... Preparing a composition based on 100 wt.h. crystalline polystyrene, 5 wt.h. chlorinated paraffin (having an average of 25 carbon atoms, the chlorine content of 70%), 0.1 wt.h. BHT; o, 035 wt.h, zinc stearate and 0.2 wt.h. benzotriazole. Samples are prepared from the composition and tested for self-extinguishing. The average burning time is 22.43 seconds. Such a composition, which does not contain benzotriazole, has an average Burn time above 60 s, Example 7. A composition based on 100 wt.h. acrylonitrile butadiene styrene resin (ABS) (containing 7% butadiene and 17% acrylonitrile), 12 parts by weight, decabromobiphenyl oxide, 5 parts by weight, SbjO and 2% by weight, of a compound of benzotriazole having formula I in which R represents -H R represents -CHjN (,). Samples are prepared from the composition and tested for self-extinguishing.
    The average burning time is 1.23 seconds.
    This composition, which does not contain a benzotriazole compound, has an average burning time of 3.48 seconds.
    Example. (Prototype). Prepare a mixture of 100 mash, high impact polystyrene with 10 mach. decabromobiphenyl, 0.2 mph. lauric acid diethanopamide and 5 May.4. antimony trioxide.
    Samples are prepared from the composition and tested for self-extinguishing.
    The burning time is 0.7 s.
    The data given in examples 1-7 show that adding to the known organic, chlorine and / or bromine-containing fire retardants of the 1, 2,3-benzotriazole derivative according to the invention improves the self-damping effect by a factor of 2-20.
    Comparison of similar compositions according to the invention (Example 4, flame retardant - Decabromobiphenyl) and the prototype (Example 8) shows that the composition according to the invention is more effective (1.4 times more.
    Thus, the composition of the invention provides a more fire resistant material.
