Thermal ignition phenomena in chain‐addition copolymerizations

摘要

AbstractThermal ignition theory has been extended to include free‐radical copolymerizations resulting in dimensionless criteria for runaway and ignition. These criteria were verified by computer simulation and preliminary experimentation. Approximate, but greatly simplified, material and energy balances describing nonisothermal copolymerizations were developed which are similar in form to those describing nonisothermal homopolymerizations. Regions of close agreement, as well as disagreement, between conversion and temperature histories from these approximations and those from the exact balances are describe
