4 Synergism between fullerenes and intumescent flame retardants

Generally, the degradation of polymers is thought to be a free radical chain reaction through (3-scission of polymer chains. Ceo, described as a radical sponge [30], has high reactivity toward free radicals, in that it has 30 carbon-carbon double bonds and can trap more than 34 free radicals [30, 36-38], Thus, Ceo can trap the macromolecular or any other radicals created by the pyrolysis of polymers and then form a gelled ball network in situ. The network can increase the melt viscosity and consequently slow the combustion of polymeric materials. Thus, in another sense, Ceo naay be considered to be a gas phase flame retardant.
