The partial phase behavior of a continuum molecular model for self-assembling semiflexible equilibrium polymers is studied via Monte Carlo and molecular dynamics simulation.We investigate the transfer from ordinary gas-liquid coexistence to the appearance of liquid crystallinity driven by excluded volume interaction between rodlike aggregates.The transfer between the two types of phase behavior is governed by a tunable anisotropic attractive interaction between monomer particles.The relation to dipolar fluid models,which are also known to form reversible chains,is discussed.
