?-polymers in crowded media under stretching force
We study the peculiarities of stretching of globular polymer macromolecules in a disordered (crowded) environment, using the model of self-attracting self-avoiding walks on site-diluted percolative lattices in space dimensions d=3 d = 3 . Applying the prunedenriched Rosenbluth chain-growth method (PERM), we construct the phase diagram of collapsedextended state coexistence when varying temperature and stretching force. The change in shape characteristics of globular polymers under stretching is analyzed as well.
