摘要：

Polystyrene-polyacetylene block copolymers with narrow molecular weight distributions were prepared by heating copolymers containing poly(phenylvinylsulfoxide) (PPVS) sequences. The length of the conjugated sequences depends on the heating temperature. The transformation from PPVS to PA was studied by spectrophotometry. The PS-PA copolymers become soluble when the PS block is large enough. These compounds can be doped, as illustrated by the change in their UV-Vis-NIR and IR spectra.
