Abstract

The present invention relates to vinyl biphenyl compounds of the formula ##STR1## wherein one of R.sup.1 and R.sup.2 is vinyl and the other is hydrogen, and the cyclic moiety A is a -2,5-, -2,3-, or -3,4- di-OR-1-phenyl moiety wherein R is a hydroxy-protecting group, polymers prepared therefrom, and methods of preparation thereof. The subject vinyl biphenyls can be polymerized and the resultant polymers deblocked to remove the R groups and provide the corresponding polymeric dihydroxybiphenyls which can be employed as redox polymers.
