Production of organometallic polymers by the interfacial technique. XXVII. Reaction variables in the synthesis of poly[oxy(dicyclopentadienylzirconium)oxycarbonylferrocenylcarbonyl]

The synthesis of polyoxy(dicyclopentadienylzirconium)oxycarbonylferrocenylcarbonyl] was studied as a function of several reaction variables. Yield varied greatly with pH, reaching a maximum around pH = 7.5; yield was greater for systems employing a saturated aqueous solution of the disodium 1,1′-ferrocene dicarboxylate falling rapidly to a plateau; yield attained a maximum as the aqueous volume was varied but decreases throughout the range studied as the volume of CHCl₃ increases; a plateau in yield was reached at around a stirring rate of 20,700 rpm. For more dilute solutions (6.7 × 10^?3M) yield is dependent on the concentration of both reactants and seeks a maximum around a stirring time of 30 sec.
