Towards a simplified approach to the modelling of the star-like molecule fluids
A theoretical approach to considering a wide spectrum of equilibrium properties of fluids formed from the four-branched molecules (e.g. four-arm star polysterene samples, four-arm block copolymers, etc.) is presented and discussed. The proposed approach is within the framework of an associative...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | A theoretical approach to considering a wide spectrum of equilibrium properties
of fluids formed from the four-branched molecules (e.g. four-arm star
polysterene samples, four-arm block copolymers, etc.) is presented and
discussed. The proposed approach is within the framework of an associative
version of integral equation theory and is based on an analytical
solution of the four-site associative hard-sphere model. Results and discussion
are explained by the comparison against Monte Carlo computer
simulation data generated for a freely-joined tangent hard-sphere model of
a star-like molecule fluid. It is shown that the proposed theory works well for
the star-like molecule fluids in homogeneous phase where it predicts the
structure for molecules with relatively long arms and at high densities. The
obtained results qualitatively reproduce the most important experimental
features of the solvation force induced between two macrosurfaces due to
the presence of star-like aggregates. |
