Influence of compositionof a dispersion medium of metane type on structural characteristics of moleculesof resins and asphaltenes
The alterations in structure of macromolecular compounds (resins and asphaltenes) depending from the composition of the oil dispersion medium as an example of model systems of methane type are studied. It has been shown that alterations in the degree of aromaticity of the dispersion medium modify structural-group characteristics in the molecules of asphaltenes: molecular weight, the number of aromatic and naphthenic cycles, the number of structural units in the molecule. Molecules of resins do not undergo significant alterations.
