  • Applications

    Trigonox® 41-C50 is an efficient initiator for the ethylene polymerization under high pressure in both autoclave and tubular processes. To obtain a wide spectrum of polymerization temperatures, combinations with other peroxides are applied in practice. Depending on reaction conditions, Trigonox® 41-C50 is active in the temperature range between 165°C and 250°C.Trigonox® 41-C50 can be used for the polymerization of styrene in the temperature range between 85°C and 105°C. Main application is the copolymerization of styrene with acrylonitrile, acrylates and methacrylates.Trigonox® 41-C50 can be used as initiator for the solution (co)polymerization of acrylates and methacrylates in the temperature range of 80-160°C, amongst others for the manufacture of coatings. Trigonox® 41-C50 can also be applied as an initiator for the bulk and suspension (co)polymerization of acrylates and methacrylates.
