N2 - A novel synthetic method combining chemo and enzymatic synthesis strategies was employed to prepare a vinyl acetate type monomer, 6-(4-methoxybiphenyl-4′-oxy)hexyl vinyl hexanedioate (VA-LC). Homo- and copolymers of VA-LC with maleic anhydride (MAn) were prepared by conventional free radical polymerization using 2,2′-azobisisobutyronitrile (AIBN) and 1,1′-azobis (cyclohexane carbonitrile) (AHCN) as an initiator at 95 and 60 °C, respectively. The thermal properties of the generated polymeric material were investigated by differential scanning calorimetry (DSC), and the optical texture was inspected by polarizing optical microscopy (POM). While the monomer VA-LC does not exhibit liquid-crystalline properties, poly(VA-LC), and the alternating copolymer of VA-LC with maleic anhydride both displayed such properties.
