![]() ![]() That is, in general f 1 and f 2 increase with an increase in the molecular weight, but f 1 and f 2 of fraction No.1 were smaller than other fractions in spite of large molecules. The same tendency was also observed for the variation of f 1 and f 2, which have been introduced for the rod-type of particles by Kuhn and Eisenschitz, respectively. Therefore, it is difficult to discuss the specific shape of the molecule clearly according to the parameter (a) of the Mark-Houwink-Sakurada equation ( =KM a). It was observed in the early study that the intrinsic viscosity increased with an increase in the molecular weight in the depolymerization under a mild condition, but the correlation between the intrinsic viscosity and the molecular weight was not observed in these reactions such as hydrogenolysis. ![]() The intrinsic viscosity and the shape factors based on it are summarized in Table 2. Yokokawa, in 1991 International Conference on Coal Science Proceedings, 1991 3.2 Molecular shape ![]()
