Abstract
A process for the preparation of polymeric compositions which comprise novel polymers and copolymers of certain 1,2-disubstituted-cyclohexadienes, aromatization of such polymers in the form of inter alia fibers, and novel aromatic polymers.
Claims7
A process for the preparation of a polymer which has aromatic rings in the backbone thereof which process comprises subjecting a polymer which has 1,2-disubstituted-cyclohexenylene rings in the polymer backbone to a suitable heat treatment in a substantially oxygen-free atmosphere such that the 1,2-substituents are eliminated from at least substantially all the cyclohexenylene rings.
