Initiation mechanisms in radical polymerization: reaction of t-butoxy radicals with allyl acrylate and with diallyl ether

Abstract

The radical trapping technique employing 1,1,3,3-tetramethyl-1,3-dihydroisoindol-2-yloxyl (1) as a scavenger has been used to study the reaction of t-butoxy radicals with allyl acrylate and with diallyl ether. With allyl acrylate, extensive H-abstraction as well as addition to both allyl and acryloyl double bonds was observed whereas with diallyl ether, the only products obtained were derived exclusively from H-abstraction.
