Wk. Busfield et al., INITIATION MECHANISMS IN RADICAL POLYMERIZATION - REACTION OF CYANOISOPROPYL RADICALS WITH STYRENE, Polymer bulletin, 38(2), 1997, pp. 149-155
The reaction of styrene with AIBN in the presence of the aminoxyl scav
enger 1,3,3-tetramethyl-1,3-dihydro-1H-isoindol-2-yloxyl is reported.
By keeping the concentration of the aminoxyl radicals very low, the ad
dition of cyanoisopropyl radicals to styrene becomes competitive with
radical trapping. Traces of adventitious oxygen give rise to some unus
ual reactions and products.
