Physical form: liquid
Trigonox® 127 is an initiator for the polymerization of (meth)acrylates and styrene.
Polymerization of Styrene Trigonox® 127 can be used for the (co-)polymerization of styrene in the temperature range of 100-135°C. The polymerization of styrene can be carried out using a combination of two or more peroxides with different activities. In practice, combinations of two or more peroxides with different activities are used to reduce the residual monomer content in the final polymer and to increase reactor efficiency. During the polymerization process, the temperature is gradually increased to ensure that the temperature required for optimal performance of each peroxide is reached. In this regard, Trigonox® 127 is often used in conjunction with more active initiators such as dibenzoyl peroxide (Perkadox L-W75) or tert-butyl peroxy-2-ethylhexanoate (Trigonox® 21S). In large-scale processes, Trigonox® 127 can be used to increase the polymerization rate.
