WebBased on the value, predict the nature of polymer. Sol: Given, M w 60,000 and M n = 40,000. Therefore, PDI = M w /M n M w /M n >1⇒ M w >M n ⇒ most probably it is a natural polymer. When the PDI value is one, it indicates mono dispersity or given polymer has monomers arranged in chains of equal length. WebLn(Ⅲ) cations are linked by carboxylate groups from (bppc) – ligands to form one-dimensional ring chains, which are further connected by the carboxylate groups of (bppc) – and (suc) 2– ligands to extend a 2D layer structure. These coordination polymers display the characteristic emission bands of Ln(Ⅲ) ions in the solid state.
