Notes:
Using Monte Carlo simulations, we investigate the rheological behavior of end-functionalized chains confined between two surfaces. The linear chains contain a reactive group ("sticker") at each end and thus, have a telechelic architecture. We vary the functionality, f, of these stickers from 0 to 3 and calculate the shear stress for different shear rates. For f〉1, the chains form a transient network that effectively blocks the stretching of the chains under shear. As a consequence, the shear stress plateaus to a constant value at high shear rates. These findings are in agreement with recent experimental studies on a comparable system. For f〉1, we also find that the limiting shear stress decreases with increasing values of f. © 2000 American Institute of Physics.
