Abstract
A process for preparing poly(p-phenylene)s comprises reacting dihydroxy aromatic compounds such as orthoquinone and bisphenols with halogen-substituted aliphatic sulfonic acids, halogen sulfonic acid, or their anhydrides. The monomers thus formed are subsequently polymerized with Ni(0) catalysts to yield the desired polymers. The monomers or polymers may be functionalized with reactive groups.
