Alkanoyl peroxide

In contrast, it is well known that styrene is a useful radical polymerizable monomer, and diacyl peroxide such as benzoyl peroxide and alkanoyl peroxide are widely used as conventional radical initiators. Since the interaction between theLUMO of diacyl peroxide (e.g., butyryl peroxide) and the HOMO of styrene become extremely weak compared to that of perfluorobutyryl peroxide (see Figure 4.3), the interaction of the SOMO of acyloxy radicals, which produce in the radical decomposition of diacyl peroxides, should interact with the HOMO of styrene to afford the radical polymerization of styrene. In contrast, styrene reacted with fluoroalkanoyl peroxides to afford not the radical polymerizable products but 1 1 adducts [PhCH(OCORp)CH2Rp] via... 

Gaylord [243] has described the bulk or suspension polymerization of vinyl chloride using a catalyst system consisting of a monomer-soluble peroxyester or diacyl peroxide as oxidant and a 6-O-alkanoyl-L-ascorbic acid as a reducing agent.
