Query: Conformations of amphiphilic diblock star copolymers   We study conformations assumed by single diblock star copolymers in a poor
solvent by means of the Gaussian variational theory and Monte Carlo simulation
in continuous space. Cases of stars with internal and external hydrophobic
blocks are analysed. While in the former case the collapsed state has an
obvious micellar shape, the latter case exhibits two nontrivial conformational
structures. Apart from the equilibrium state of a globular hydrophobic core
with hydrophilic daisy loops, one also finds here a metastable state of
outstretched hydrophilic blocks with hydrophobic subglobules at their ends.
Such a state appears to be rather long-lived during the kinetics of collapse of
a swollen star. The plots of monomer densities and other observables computed
by both techniques are found to be in good agreement with each other.
