Abstract
Dynamic Monte Carlo simulations are performed for lattice self-avoiding tail-like polymer chains with one end attached to a non-interacting and impenetrable flat surface. The configurational entropy STL of the tail-like chain is determined by the scanning method. The entropy STL is smaller than that of the free chain without surface SF. The entropy drop ΔS=SF-STL increases linearly with ln n for short chains and increases linearly with n for long chains. However, the average entropy drop per bead ΔS/n decreases with n, indicating that the average effect of the surface on one chain bead decreases with the increase in chain length.
