Why is the mechanism of traditional free radical polymerization characterized by slow initiation, rapid growth and rapid termination?
In chain initiation, the decomposition of the initiator is an endothermic reaction with high activation energy, so the rate is small. The combination of free radicals and monomers releases heat. In chain growth, the combination of monomer free radicals and monomers has low activation energy, strong heat release, and therefore fast.
The chain termination activation energy is very low, and the termination rate constant is extremely high, so it is faster,,,,,, not perfect, but that’s about it,,, I think the first one found on Baidu search is okay, you can take a look,
