There has been a considerable e amount of research on the synthesis of A-B rod-coil amphiphilic block copolymers with various synthetic routes because these polymers have shown interesting properties such as phase separation behavior and self-assembly phenomena in different volume fractions and selective solvents. However, the research about rod-rod block copolymer of synthesis and self-assembly is still a pristine area in the polymer chemistry field. Well-defined rod-rod block copolymer of poly(furfuryl isocyanate)-b-poly(n-hexyl isocyanate)s, were synthesized with quantitative yields and controlled molecular weights by anionic polymerization in tetrahydrofurane (THF) at -98 oC. Synthesized block copolymers were characterized with SEC, NMR, and IR, which showed the proof of well-controlled rod-rod block copolymers. Synthesized polymers demonstrated the self-assembly, phase separation behavior and micelle formation in selective solvent of one block was verified using TEM and AFM. |
