43. Note that these values may also argue in favor of a fully efficient bimetallic initiating system, though detailed mechanistic issues have not been addressed so far.
44. It is noteworthy that the produced MMA/n-BA block copolymers have lower molecular weight distributions than those of the P(n-BA) homopolymers. Such observations, i.e., P(n-BA, PDI = 1.26-1.51 vs PMMA-b-P(n-BA), PDI = 1.18, have been also briefly reported by Chen et al. with a zirconocene initiator; see ref 2k.
