.Application
1. Polymerization of styrene
TBPB can be used for the polymerization and copolymerization of styrene in the temperature
range of 100-140°C. During polymerization the temperature is increased in steps.
2. Polymerization of acrylates and methacrylates
TBPB can be used as initiator for the solution (co)polymerization of acrylates and
methcrylates in the temperatures range of 100-170°C, amongst others for the coatings.
TBPB can also be applied as an initiator for the bulk and suspension (co)polymerization of
acrylates and methcrylates.
3. Polymerization of ethylene
TBPB is an efficient initirtor 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. TBPB is active in the temperature range of 220-270°C.
4. Other applications
TBPB can also be used for the (co)polymerization of acrylonitrile and vinyl acetate.
