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 fibres, and novel aromatic polymers.
Claims4
A process for the preparation of polymeric compositions comprising a cyclohexadiene homo- or copolymer which process comprises treating a polymerisable composition which comprises a 1,2-disubstituted-cyclohexa-3,5-diene or homologue or analogue thereof under polymerisation conditions for the polymerisable composition, which 1,2-substituents, which may be the same or different and are selected from the group consisting of acyloxy, carbonate, alkoxy, amide, halide, thioester, urethane and xanthate.
