Trigonox 41-C50

tert-Butyl peroxyisobutyrate

CAS Number: 109-13-7

Physical form: liquid

Trigonox® 41-C50 is an initiator for the (co)polymerization of ethylene and styrene.


Trigonox® 41-C50 is an effective initiator for high-pressure ethylene polymerization in autoclave and tube processes. In order to obtain a wide range of polymerization temperatures, combinations with other peroxides are applied in practice. Depending on the reaction conditions, Trigonox® 41-C50 is active in the temperature range from 165°C to 250°C. Trigonox® 41-C50 can be used for styrene polymerization in the temperature range from 85°C to 105°C. The main application is the copolymerization of styrene with acrylonitrile, acrylates and methacrylates.Trigonox® 41-C50 can be used as an initiator for the solution (co)polymerization of acrylates and methacrylates in the temperature range of 80-160°C, including the manufacture of coatings. Trigonox® 41-C50 is also used as an initiator for the native polymerization and suspension (co)polymerization of acrylates and methacrylates.
