Addition (chain-growth) polymerization reactions often terminate by combination or disproportionation. However, there is another class of deactivation reactions, called chain transfer reactions, which are usually relevant to the final degree of polymerization (dp). How might you expect the dp of a polymerization reaction deactivated by chain transfer compare/contrast with polymerizations terminated by combination or disproportionation?
