Abstract

Abstract: The properties of polymer fluids are closely related to the structure of polymer chains and their dynamical behaviors. When a single polymer chain diffuses in a matrix, the properties of this single chain depend on the topology of the matrix very much. In this paper, using lattice Monte Carlo simulation method, the static and dynamical properties of the target single chain in polymer matrices are studied, and four types of topology combinations are investigated with increasing chain length of matrix. It is found that the target ring chain is more sensitive to the topology of matrix than that of linear chain, which implies that diffusion mechanism of a single ring chain in the linear matrix might be changed.
