(57) Fireproof polymer additive is created from the non-toxic components in such a way that the melt of waterless mixture of ammonium polyphosphate, pentaerythritol and preferably melamine and/or urea, too, is produced, with temperature ranging from 240 °C to 350 °C; the common melt is maintained at the said temperature for at least 30 seconds, subsequently it is left to cool and the solidified melt is disintegrated into particles smaller than 200 pm, preferably smaller than 50 pm, especially preferably smaller than 10 pm. Each of the two components can at the entry form 5 to 95% of the mass of the final mixture. In case of the realization with three or four components, each of the components can at the entry form 5 to 50% of the mass of the final mixture. The fireproof polymer additive is added to the basic material in ratio of 1 % to 80% of the share of the mass of the resulting matter; it can be added into a thermoplastic or into some component of the epoxy resin or polyester resin or vinyl ester resin, or into polyurethane base or into elastomeric rubber or bioplastic. Fireproof polymer additive is highly fire resistant and smoke resistant.
