Di-Tert Butyl Peroxide (DTBP)
Di-tert-butyl peroxide or DTBP is an organic compound consisting of a peroxide group bonded to two tert-butyl groups. It is one of the most stable organic peroxides, due to the tert-butyl groups being bulky. It is a colorless liquid.

DI-TERTIARY BUTYL PEROXIDE (D.T.B.P) as a ready source of free radicals, finds applications in production of the following high molecular weight polymers; polyacrylates high styrene resins, polystyrene, acrylonitrile butadiene styrene resins, styrenated esterified epoxy resins and alkyl polymers among others. It may also be employed effectively as a coupling and vulcanization agent in the production of vulcanized rubber. Another general application is in the modification of bodying of unsaturated oils. it acceptance as a polymerization initiator where cure temperatures of 212o F (100oc) or more.
