Abstract: | The effect of stiffness in a 2D living polymer system is investigated by Monte-Carlo simulation in a canonical ensemble. As
the flexibility decreases, the mean chain contour length decreases and goes through a local maximum. The mean end to end square distance shows a non-monotonic behaviour due to the
coil-to-rod transition and the decrease in chain contour length. Near the maximum of chain ordering in the bulk, the chain
length distribution adapts itself to increase the configurational entropy. With the parameters used in this simulation, it
seems that the effect of the stiffness for high stiffness is to decrease as in the isotropic case, since the ordering decreases again.
