Abstract

A general approach is proposed to calculate the attenuation of spin echo diffusion and the self-diffusion coefficients D of linear polymers with different average molecular weights M w . It was shown that the changes in the topological structure of linear polymers resulted from the formation of a physical entanglement network at M w > 105 are responsible for the experimentally observed anomalous diffusion D(M w ).

Keywords
