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 quatemization 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.
