Controlled radical polymerization of vinyl pivalate (VPi) was achieved by cobalt-mediated radical polymerization (CMRP) using cobalt(II) acetylacetonate (Co$(acac)_2$) and 2,2'-azo-bis(4-methoxy-2,4-dimethylvaleronitrile) (V-70). Poly(vinyl pivalate) (PVPi) chains having controlled molecular weights and low polydispersities ($M_w/M_n$=1.05-1.29) were successfully synthesized. PVPi macroinitiator ($M_n$=11,100 g/mol, $M_w/M_n$=1.13), which was end-capped by Co$(acac)_2$ was used to successive CMRP of well-defined PVPi-b-poly(vinyl acetate) (PVPi-b-PVAc) and PVPi-b-poly(acrylonitrile) (PVPi-b-PAN) block copolymers at 30 DC. The polymerization of PVPi-b-PV Ac was performed via a degenerative chain transfer (DT) mechanism using an excess of V-70. PVPi-b-PAN was synthesized via a reversible termination (RT) mechanism in DMF.
