Molecular dynamics modeling and experimental
measurements are used to identify factors which reduce
flammability by promoting the formation of heat
resistant chars during the thermal degradation of
polymers. Computer movies of the calculated
trajectories reveal that cross-linked model polymers
tend to undergo further cross-linking when burned. The
presence of strong potential energy interactions with a
surface or filler further facilitates the formation of
high molecular weight, thermally stable chars.
