Abstract
Polyphenylene is prepared by exposing a poly(1,2-disubstituted-cyclohexa-3,5-diene) precursor to ultraviolet light in the presence of an acid catalyst. The acid catalyst is activated by the ultraviolet radiation and forms polyphenylene by aromatizing the cyclohexene rings of the poly(1,2-disubstituted-cyclohexa-3,5-diene).
