  • Applications

    Polymerization of styreneTrigonox® 127 may be used for the (co)polymerization of styrene in the temperature range of 100-135°C. In practice, combinations of two or more peroxides with diverging activities are used to reduce the residual monomer content in the final polymer and to increase reactor efficiency. During polymerization, the temperature is increased incrementally to insure that the temperature necessary to attain the optimum properties for each peroxide is reached. In this respect, Trigonox® 127 is often used with more active initiators, such as dibenzoyl peroxide (Perkadox L-W75) or tert-butyl peroxy-2-ethylhexanoate (Trigonox® 21S). In a mass process Trigonox® 127 may be used to increase the rate of polymerization.
