    • There are, however, a few exceptions. For one, the initial peak in the distributions (seen in Fig. 4a of Paper I) for beads in trains now broadens and no longer occurs at 100%, but rather at some depressed value. This reflects the fact that the early-adsorbing chains, which arrive to find a bare surface, do not collapse onto the surface as completely in the presence of impurities. This depressed value varies with the impurity cases considered. In the cases with inactive surface impurities, as well as that with few (30%) inactive chain impurities, this value is only slightly depressed, and the distributions still exhibit an early peak at high percentages (>90%). The depression is more dramatic in cases where the impurity surface sites are repulsive. As the fraction of repulsive impurity surface sites increases, this peak percentage decreases to such an extent that by the point where half of the surface sites are repulsive, this value is virtually reduced all the way to its equilibrium value. There is then little appreciable evolution over time in any of the distributions, except for normal fluctuations.
