General description

Benzoyl peroxide is an organic peroxide commonly used to initiate free radical polymerizations and to form copolymers through grafting reactions. It is also used as an oxidizer during chemical reactions.

Application

Benzoyl peroxide is used:

  • In the direct N–O bond synthesis from 1,2-diamines.
  • As an initiator in the synthesis of the cross-linked unsaturated copolymer by cross-linking methyl methacrylate with Poly (2-butene maleate) polyester.
