Abstract
Poly(1,4-phenylene)-block-polystyrene-block-poly(1,4-phenylene) (PPP-b-PS-b -PPP) blocks copolymers were synthesized by chemical modification of a prec ursor copolymer. After characterization by Size Exclusion Chromatography (S .E.C) and W-Visible spectroscopy, triblock copolymers were studied in CS2 s olution at room temperature by neutron-scattering analysis. These triblock copolymers are highly aggregated, A ribbon model seems to give the best fit for the PPP core.
