。Application
Polymerization of ethylene
LQ-TBPI 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, LQ-TBPI is active in the temperature range of 165℃ and 250℃.
Polymerization of styrene
LQ_TBPI can be used for the polymerization of styrene in the temperature range between 85℃ and 105℃. Main application is the copolymerization of styrene with acrylonitrile, acrylates and methacrylates.
