Unformatted text preview: t-butoxy radicals undergo ß-scission to acetone and methyl radicals. A major fraction of the methyl radicals add to the allyl functionality of the triallyl isocyanurate (TAIC) coagent to form radical adducts. Only a minor fraction of methyl radicals is involved in transfer reactions with fluoroalkyl bromide sites on polymer chains to form methyl bromide and polymeric radicals. If the radical trap concentration is reduced considerably, the amount of methyl bromide increases by up to a factor of two, still relatively low versus the total amount of methyl radicals produced....
