Description
  • Práce je věnována výzkumu roztokových vlastností pentabloku typu polystyren-butadien v selektivním rozpouštědle n-heptanu metodami rozptylu světla a neutronů Byla pozorována tvorba norozpustných domén o rozměru cca 10 nm, které při vyšších koncentracích byly uspořádány do kubické mřížky. Relaxační dynamika těchto domén zachycených v uspořádaném fyzikálním gelu byla pozorována dynamickým rozptylem světla. (cs)
  • We have examined solutions of a polystyrene-polybutadiene pentablock copolymer in n-heptane, a strongly selective solvent for polybutadiene. Small angle neutron scattering reveals domains about 10 nm in radius formed by the association of ~200 polystyrene blocks. Dynamic light scattering measurements on 8 and 9 % samples showed a relaxational mode related to the local dynamics of polystyrene domains trapped in the gel formed by bridring the domains.
