Nouryon Trigonox 127 tert-Amyl peroxybenzoate 4511-39-1

Trigonox 127
Tert-amyl peroxybenzoate
CAS Number: 4511-39-1
Physical Form: Liquid
Trigonox® 127 is an initiator for the polymerization of (methyl)acrylates and styrene.
Applications
Styrene Polymerization: Trigonox® 127 can be used for the (co)polymerization of styrene within a temperature range of 100–135°C. In practice, a combination of two or more peroxides with different activities is used to reduce the residual monomer content in the final polymer and improve reactor efficiency. During the polymerization process, the temperature is gradually increased to ensure that the temperature required for each peroxide to achieve optimal performance is reached. In this context, Trigonox® 127 is typically used in combination with more active initiators, such as dibenzoyl peroxide (Perkadox L-W75) or tert-butyl 2-ethylhexanoate peroxide (Trigonox® 21S). In large-scale processes, Trigonox® 127 can be used to increase the polymerization rate.
