✦ Synopsis

Conformational statistics of an ideal polymer chain in the vicinity of the bifurcation region of a narrow pore system is considered. It is shown that the bifurcation region plays the role of an effective entropic trap. Due to this fact the chain adopts globular conformation with the average dimensions of the order of the dimensions of the bifurcation region. It is concluded that the statistical properties of an ideal polymer chain and of random walks near the bifurcation point are essentially different.
