## Abstract **Summary:** We present and assess the use of nonโequilibrium molecular dynamics (NEMD) simulation method for the direct study of the linear viscoelastic behavior of polymer melts. The polymer melt is modeled by a collection of repulsive, anharmonic multibead chains subjected to small a

The viscoelastic properties of concentrated polymer solutions are discussed on the basis of the fixed tube model proposed by de Cennes. It is shown that the steady flow viscosity is proportional to M3, where M is the molecular weight, and that the relaxation spectrum exhibits a hump in the relaxatio
Low molecular weight, low viscosity poly(pheny1ene sulfide) (PPS) has been cured in the melt state to examine effects of curing time and temperature on the melt-state dynamic viscoelastic behavior. It was found that the Newtonian behavior of the uncured material could largely be retained if melt cur
