Abstract:  The influence of triethylenetetramine on the emulsion polymerization of styrene initiated by polypropylene polyhydroperoxide or AIBN at 30°C as well as its influence on the polymerization of styrene initiated thermally at 75°C was investigated. The results obtained indicate that the investigated amine in addition to the activation of the decomposition of peroxides of oxidized polypropylene positively influences styrene polymerization also in another way. Because of its basic character it changes the pH and by that to some extent also the character of emulsion. Owing to its structure it can influence the polarization of the double bond of styrene and thus facilitate its bonding to a growing radical. These effects of triethylenetetramine considerably raise the rate of styrene polymerization in the investigated emulsion polymerization systems.
