Notizen: Polypropylene containing a bromophosphorous flame-retardant exhibits a higher mass burning rate - in the atmosphere containing more than 30 vol % of oxygen - than nonretarded resin. These prodegradative reactions in combustion can be eliminated only by using a high concentration (ca. 40 phr) of inorganic alumina trihydrate. A method for distinguishing the physical and chemical effects of flame retardants is described.

Notizen: The course of pyrolysis, thermooxidation, flame combustion and glowing combustion has been observed with differently treated cellulose samples by means of thermoanalytical methods. The impregnation of cellulose materials by inorganic salts produces a less combustible material, less stable at relatively low temperatures, yet giving more of the solid residue resistant to pyrolysis and combustion processes. The more thermally stable cellulose derivatives, but with insufficient resistance to flame and particularly glowing combustion, have been obtained by cyanoethylation and grafting of acrylonitrile on to cellulose.
