Initiation Mechanisms in Radical Polymerization: Reaction of t-Butoxy radicals with Allyl methacrylate

Abstract

The radical-trapping technique employing 1,1,3,3-tetramethylisoindolin- 2-yloxyl (1) as scavenger has been used to study the reactions of t-butoxy radicals with allyl methacrylate (2). Extensive hydrogen abstraction as well as addition to both allyl and acryloyl double bonds was observed. One unusual feature of the reaction, the formation of considerably more (Z)- alkene than (E)- alkene from trapping of radicals derived from the allyloxy moiety, is also discussed.
