eta ⁵C₅H₅Fe eta ⁶C₆(CH₃)₅CH₂-.

In the reported experiments, new polymer-supported catalysts that contain the redox cyclopentadienyl iron moiety left bracket eta **5C//5H//5Fe eta **6C//6(CH//3)//5CH//2- right bracket ** plus were prepared with polyvinylchloride (PVC) as support. The active center is attached as a pendant organometallic moiety in the side groups of the PVC chain. Metallocenic groups and the supported polymers with various Fe content were analyzed by spectroscopic techniques and by polarographic and cyclic voltammetry. The absorption spectra show a similar profile to that of the nonsupported cation, which indicates that the supported polymer contains side groups in the chain with metallocenic structures. The new polymer-supported catalysts were characterized by viscometric measurements and by differential calorimetry (DSC). A linear relationship between intrinsic viscosity/ left bracket eta right bracket and the Fe content was observed. The glass transition temperature (T//g) values are higher than those of PVC without modification.
