Gas diffusion in branched and crosslinked polymers: A model of treelike clusters
The correctness of the fractal model of treelike clusters for describing the diffusion processes in branched (crosslinked) copolymers is shown. As in the fractal model of gas transport processes, for the copolymers investigated, the main role of diffusivity was to change the connectivity of the macromolecule, characterized by its spectral dimension.
