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.
阴离子聚合引发剂可用于制备具有保护胺基功能团的聚合物。胺官能团包括第一保护基,可以是芳基烷基、甲基、烯丙基或三级烷基基团。另一个胺保护基可以与第一个保护基相同。或者,第二保护基可以与第一个保护基不同,在这种情况下,它被选择为具有对去除芳基烷基、甲基、烯丙基或三级烷基保护基的试剂具有差异稳定性的基团。
