successfully carried out without significant decomposition of the living polymer end
[162]. The polymer chain end is living within such residence times. Moreover, the
subsequent reaction of the living polymer end with a different alkyl methacrylate leads
to the formation of a block copolymer having narrow molecular-weight distribution
(Table 4).
