The configuration-bias-vaporization Monte Carlo simulation method developed by Yan et al . has been used to simulate the phase equilibria of AB random copolymers based on the close-packed Flory-Huggins lattice model. Random copolymers are represented as linear chains consisted of r A segment A and r B segment B with segment-segment attractive interaction energy parameters ε AA / kT=-1.0/T *, ε AB / kT=-0.8/T * and ε BB / kT=-0.6/T *. The phase diagrams of random copolymers with a chain length up to 200 segments are obtained. The corresponding critical points for different chain lengths with fixed chain composition are also calculated.

Random copolymers are represented as linear chains consisted of r A segment A and r B segment B with segment-segment attractive interaction energy parameters ε AA / kT = -1.0 / T *, ε AB / kT = -0.8 / T * and ε BB / kT = -0.6 / T * phase diagrams of random copolymers with a chain length up to 200 segments are obtained.
