✦ Synopsis

We introduce the parameter of probability of movement and study the dynamics of polymer chains by using the improved body-centred cubic lattice model. The model can approach to simulate the dynamics of real polymer chains. We find that the relaxation times obey the relation TR( ) ~ (N -1)2°5/P °Ts in the absence of excluded volume and the relation Trt(P) ~ (N -1)233/P °'95 in the presence of excluded volume, also the relation Tk(P)~ Tk(1)/PPk (ill = #2 = 0.77,/~3 = 0.90) in the absence of excluded volume. Comparisons with theoretical predictions are made.
