Partially conjugated poly(arylenevinylene)s

摘要

A process for preparing a precursor of a poly(arylenevinylene) wherein some of the vinylene groups are replaced by ethylene groups which comprises subjecting a polymer which possesses recurring units of the formula -Ar-CHX-CHR<3>- wherein X represents a leaving group, Ar represents an arylene or heteroarylene group and R<3> represents an alkyl group, to a radical reaction so as to eliminate some of the X groups is provided together with the polymer obtained thereby and those obtained from these precursors.
