The involvement of 1,6-diphenyl-1,3,5-hexatriene and 1,8-diphenyl-1,3,5,7-octatetraene in the radical polymerization of methyl methacrylate

The α, ω-diphenyl derivatives of 1,3,5-hexatriene and 1,3,5,7-octatetraene strongly retard the radical polymerization of methyl methacrylate (MMA); the effects are greater when initiation is achieved with benzoyl peroxide than when azobisisobutyronitrile is used. The tetraene and the triene are respectively 575 and not less than 240 times as effective as MMA in capturing the benzoyloxy radical at 60°C.
