Precise Tailoring of polymer chains and characterization provide understanding on the role of the chemical structures onto physical behaviors of polymers. In this talk, labelled polystyrene with single ionic group from unique polymerization kinetic of 1,1-diphenylethylene (DPE) will be discussed. Single ionic group per chain was labelled into polystyrenes systematically using sequence controlled anionic polymerization. The microstructures were characterized using x-ray scattering, and critical role of functional group location in polymer chains on aggregation and fractal structure formation was investigated. In addition to this, thermal and viscoelastic properties of nearly perfect alternating copolymer of 1,1-diphenylethylene (DPE) and butadiene and its selectively hydrogenated polymers will be discussed. |
