SYNTHESIS AND CHARACTERIZATION OF Fe(II)-COORDINATED PS-b-P[NIPAM-co-(VBC-Fe-DMAP)] BLOCK COPOLYMERS

In this work, a new type of block polymers, polystyrene-b-poly[(N-isopropyl acrylamide)-co-(vinyl benzyl chloride)] (PS-b-P(NIPAM-co-VBC)), was prepared via reversible addition fragmentation transfer polymerization, then pentacyano(4-(dimethylamino pyridine))ferrate (Fe-DMAP) was attached to VBC units through a quaternization process. The Fe(II)-coordinated PS-b-P[NIPAM-co-(VBC-Fe-DMAP)] block copolymers were characterized by 1H-NMR, FT-IR and TGA. The self-assembly behavior of the block copolymers was also investigated and the micelle morphology was characterized by TEM. It was found that the PS-b-P(NIPAM-co-VBC) block polymer and Fe-coordinated block copolymer could both form spherical micelles in DMF/MeOH mixed solvent.
