Aggregation of n-doped polystyrene-polyparaphenylene block copolymers: a neutron scattering study

Polystyrene-polyparaphenylene (PS-PPP)block copolymers are soluble in good solvents of polystyrene. They form stable aggregates made up of a dense PPP core surrounded by a diffused PS shell which behave like colloïdal particles, provided the PPP sequence is large enough. The n-doping of such an aggregated structure has been investigated, by use of small angle neutron scattering.
