During propagation step of a free-radical chain-growth polymerization does the polymer actually grow or chain extend.
What is radical chain-growth polymerization?
- The process of free-radical chain growth in polymers. Common free-radical reactions include polymerizations using free-radical mechanisms.
- The formation of radicals is the initiation, the development of the products is the propagation, and the ending of the free-radical chain reactions is the termination.
What distinguishes step growth polymerization from chain growth polymerization?
- The polymer chain in chain growth always expands one monomer at a time.
- The polymer chain doubles with each step of step development. The polymer chain's rate of expansion is drastically different in these two situations as a result.
- Every coupling step causes chain growth, which causes the chain length to gradually expand.
