Abstract
Anionic polymerization initiators useful in the preparation of polymers having a protected amine functional group. The amine functionality includes a first protecting group, which can be aralkyl, methyl, allyl or tertiary alkyl group. The other of the amine protecting groups can be the same as the first protecting group. Alternatively, the second protecting group can be different from the first protecting group, in which case it is selected to have differential stability to agents used to remove the aralkyl, methyl, allyl or tertiary alkyl protecting group.
