제목 Synthesis of Rod-Coil Block Copolymers of Aromatic Polyamide and Polystyrene and Their Self-Assembly
초록 The interest in rod-coil block copolymers is due to their unconventional phase buhavior in comparosion with common coil-coil type diblock copolymers. We have recently achieved control over molecular weight and polydispersity of poly(benzamide)s by chaim-growth polycondensation. Here we report the synthesis of rod-coil polybenzamide-b-polystyrene. Living anionic polymerization of St was carried out, followed by quenching with CO2 to yield PStCOOH. Phenyl ester-terminated polystyrene(MI) was obtained by the reaction of PStCOOH and phenol with DCC, DMAP and PTSA. Macroinitiator MI was used for the chain growth polycondensation for polybenzamide. The GPC traces showed a clear shift toward the higher molecular weight region.
