98 Tert-Butyl Peroxy Benzoate  

Molecular formula C11H14O3  Molecular weight 194.23  CAS NO. 614-45-9 TBPB is an efficient initiator for the ethylene polymerization under high pressure in both autoclave and tubular processes,also suitable for crosslinking of EPDM rubber compounds at ambient temperature within some weeks. TBPB is a low volatility ,high purity,liquid, aromatic peroxuester.it is effective as medium of a broad spectrum of monomers e.g .styrene.ethylenn,acrylics.it is also used to cure (copolymerzation) unsaturated resins . Tert-Butyl peroxybenzoate (TBPB) a chemical compound from the group of peresters. It is often used as a radical initiator in polymerization reactions, such as the production of LDPE from ethylene, and for crosslinking, such as for unsaturated polyester resins.  TBPB is a clear light yellow liquid, which is little soluble in water but well in many organic solvents such as ethanol or phthalate.  As peroxo compound, TBPB contains about 8.16 wt% of act…
