The radiochemical polymerization of styrene in aqueous suspension was studied using polyvinyl alcohol as the dispersing agent. The conversion curves obtained with three intensities of gamma radiation are linear up to 60% conversion. The slope of the curves is proportional to the radiation intensity to the 0.65 power. The polymer formed includes an insoluble fraction whose importance decreases with the conversion. The average molecular masses of the soluble polymer fraction remain constant during the reaction and are inversely proportional to the square root of the intensity. These results are compared with results obtained previously during the study of the radiochemical polymerization of styrene in mass. From these data the value of the radiochemical yield for the beginning of chains was determined to be of the order of 2 to 4. The mechanism of the radiochemical polymerization in suspension is discussed. (tr-auth)
