N ‐Isopropyl‐4‐vinylbenzylamine (PVBA) was synthesized and used as an initiator for the polymerization of methacrylates to synthesize macromonomers with terminal styrenic moieties. LiPVBA initiated a living polymerization and block copolymerization of methyl methacrylate, 2‐( N,N ‐dimethylamino)ethyl methacrylate and tert ‐butyl methacrylate and produced polymers having well‐controlled molecular weights and very low polydispersities ( M̄ w / M̄ n < 1.1) in quantitative yield. 1 H NMR analysis revealed that the polymers contained terminal 4‐vinylbenzyl groups. The macromonomers were reactive in the copolymerization with styrene.
