Chain transfer Chair conformers

The branching on chains of low-density polyethylene results from a back-biting reaction in which the radical end group abstracts a hydrogen from the fourth carbon back (the fifth carbon in the chain). Abstraction of this hydrogen is particularly facile because the transition state associated with the process can adopt a conformation like that of a chair cyclohexane. In addition, the less stable 1° radical is converted to a more stable 2° radical. This side reaction is called a chain-transfer reaction, because the activity of the end group is transferred from one chain to another. Continued polymerization of monomer from this new radical center leads to a branch four carbons long ... [Pg.577]
