Abstract: Compounds containing chlorine, bromine or phosphorus were bonded on surface-grafted polypropylene with 2,3-epoxypropyl methacrylate by means of epoxy groups. The polymer with bonded monophenylphosphoric acid containing 0.4—1.2 mass % phosphorus in the solid phase had properties of a self-extinguishing material. It was proved by thermal analysis that some fixed compounds retard effectively exothermal reactions in the material, when they are heated in air. The increased stability in the temperature range 200—300 °C could be also significant for the polymer protection during its thermal processing.
