Synthesis of Titanium, Zirconium and Hafnium Modified PolysaccharidesDextran has been modified employing the classical interfacial polycondensation technique through reaction with Group IV B bicyclopentadienylmetallocene dichlorides. Product yields, both percentage and weight, follow the general trend Hf>Zr>Ti consistent with the Hard-Soft Acid Base theory. Dextran is employed as a representative polysaccharide.
