摘要：

High-pressure apparatus (up to 1 GPa) for viscosity measurements (using the capillary method) of a high-viscous medium has been constructed. High-pressure phases of pure castor oil and methyl alcohol doped castor oil, which had been obtained earlier, were generated and their viscosity measured. Values of viscosity as high as 160 kPas for pure castor oil and 60 kPas for methyl alcohol doped castor oil (about 5 of volume %), at a small shear rate parameter equal to about 0.1 s(-1), were measured and their structural (tixotropic) type viscosity (consistency) were discovered.
