摘要

Trioctylammonium p-styrenesulfonate (SS-TOA), is polymerized using the BlocBuilder uni- molecular initiator and SGI. Polymerizations are controlled for low theoretical molecular weight, resulting in low polydispersities and a linear increase in M_n up to≈35% conversion. The product of the propagation rate constant and the equilibrium constant for SS-TOA is 1.4- 2 times that of styrene at the same temperature, suggesting its suitability as a controlling co-monomer for BlocBuilder-mediated NMP with methacrylates. SS-TOA is effective as a controlling co-monomer for gradient polymerization with GMA using NHS-modi- fied BlocBuilder. The resulting copolymer has a narrow, monomodal MWD and a linear increase in M_n with conversion, suggesting SS-TOA is an effective NMP co-monomer.
