Pseudo Phenyl-Polyphenylene vinylene (PhPPV) sequences have been synthesise
d by dehydrogenation of quasi alternated 1,3 cyclohexadiene (CHD) - styrene
(St) copolymers prepared by anionic copolymerisation initiated by sec butyl
lithium in cyclohexane. This method allows the preparation of block copolym
ers including phenyl PPV sequences.
