“…63 In this last case, the labile initiator fragment confers to the polymer chain degradability at a precise location, allowing the controlled reduction in molecular weight and the degree of branching, but also the formation of certain functional endgroups. Regarding reduction in size and degree of branching upon degradation, polymers made using degradable initiators have been transformed to smaller entities of simpler architecture, with most notable examples the scission of linear homopolymers into two equal pieces, 42,45,47,52,53,60 the conversion of ABA triblocks into diblocks, 43,44,51 the decomposition of star polymers into the constituting arms, [48][49][50] the separation of dumbbell polymers to two star polymers, 46,54 and the conversion of homopolymer model networks to star homopolymers. 57,59,61,62 Regarding the formation of functional end-groups, these are the residues of the labile initiator fragment after its degradation, remaining in the polymer.…”
