Tert.Butylperoxybenzoate, [<= 50% with inert inorganic solid] is a clear, colorless to slightly yellow liquid with a mild, aromatic odor. It is effective as a medium temperature initiator for the polymerization and/or cross-linking of methyl methacrylate, acrylonitrile, isoprene, styrene, and butadiene. Low-density polyethylene of excellent mechanical properties is obtained when using this peroxide as an initiator. This peroxide is also used in various organic syntheses involving coupling reactions of olefins and paraffinic compounds as well as phenolic derivatives.
