Which process inhibits polymer chain propagation when free radical polymerization energy input decreases?

💡 Explanation

When energy input decreases, free radical populations diminish, which lowers the rate of monomer insertion, increasing the probability of two growing chains reacting and terminating by recombination. Therefore premature chain termination results, rather than diffusion increases, chain transfer enhancement, or faster initiator decomposition which require different energy-dependent mechanisms.
