Abstract:The computer simulation of polymer system with limited chain length and high density was performed on a square lattice in order to study the details of the disordered vs ordered states of bulk polymers as a function of chain flexibility and temperature.The static and dynamic properties of athermal chain systems are in agreement with polymer melts.Assuming an intramolecular energy E_c and an intermolecular energy E_p,we have simulated metastable nematic ordered state and lamellar ordered state by introducing E_p/E_c=0 and E_p/E_c=l respectively.The relation of these results to the real symmetrical polymers such aspolyethylene was discussed.Also,the trends of chain regular folding were observed in these metastable ordered states.
Keywords:Computer simulation  Phase transition  Polymer
