Abstract
Photo-induced dehydrohalogenation of halogenated polymers produces a conjugated polyene and/or polyyne. The mechanism for dehydrohalogenation of polyvinyl chloride) (PVC) was discussed in terms of the C-CI bond cleavage and the following zip-dehydrochlorination. Irradiation of PVC, chlorinated PVC, and poly(vinylidene chloride) with an Ar ion laser or excimer lasers was carried out in order to synthesize longer conjugation polyene and/or polyyne. Irradiation with a KrF excimer laser in vacuum produced a polyyne structure with a conjugation length of about 30 carbon atoms.
