Poly(vinyl laurate) (PVL) and poly(vinyl stearate) (PVS) were synthesized by means of cobalt-mediated radical polymerization. The efficiency of cobalt(II) diacetylacetonate (Co(acac)2) was demonstrated for controlling the radical polymerization of these monomers in solution. PVL-b-PVS diblock copolymers could be synthesized using two strategies: (1) Sequential addition, and (2) macroinitiator technique. The resulting materials were characterized by differential scanning calorimetry, revealing that both blocks exhibit side-chain crystallinity and phase segregate in the bulk.
