Synthesis and Characterization of Vinyl Substituted 2,2-Bisferrocenylpropane and Corresponding Polymers

Abstract

The homopolymer of 6-vinyl bisferrocenylpropane and copolymer of 6-vinyl bisferrocenylpropane and 6,6'-divinyl bisferrocenylpropane were obtained from ferrocene and acetone via a series of reactions. The monomers and polymers were characterized by elemental analyses, IR spectra and IHNMR. The thermal stabilities of the polymers were studied through DTA-TG. The results show that the solubility of the copolymer of 6-vinyl bisferrocenylpropane and 6,6'-divinyl bisferrocenylpropane is very poor and its thermal stability is obviously higher than the homopolymer of 6-vinyl bisferrocenylpropane. The reason for it is that the monomer of 6,6'-divinyl bisferrocenylpropane has two vinyl groups, so the grafting degree of the corresponding polymer is much larger than the homopolymer of 6-vinyl bisferrocenylpropane.
