Abstract:  By the method of experimental designing, its statistical evaluation and by using hydroiodic acid we looked for conditions of quantitative decomposition of peroxides of isotactic powdered polypropylene initiating styrene polymerization in the emulsion system in the presence of FeSO4 —triethylenetetramine chelate. The degree of decomposition of peroxides of isotactic powdered polypropylene was determined by the results of styrene polymerization in their presence. The investigated peroxides decompose quantitatively by employing HI in the concentration range 5.5—7.58 mol l-1 at 70—90°C during 6—7 h. These conditions exclude the possibility of simultaneous quantitative determination of peroxides for their thermal decomposition proceeding parallelly at the above-mentioned temperatures.
