Synthesis and Properties of Polyurethanes Prepared from Dihydric Alcohol of 2,2-bisferrocenylpropane and Toluene Diphenylmethane Diisocynate

A series of new diferrocene-containing polyurethanes were synthesized by the reaction of diphenyl methane diisocynate with dihydric alcohol of 2,2-bisferrocenylpropane.The synthesis conditions were optimized,and the influence of reaction temperature on the molecular weights of polymers was also studied.The compositions and structures of these polymers were characterized by elemental analysis, IR and ~1H NMR.The molecular weights of polymers were determined by GPC,the thermal stability was tested using DTA-TG,and the properties of oxide-reduction of these polymers were measured by cyclic voltammetry.
