title: [Investigation of the structure of macromoleculare gels II: analysis of viscosity curves].
abstract: Viscosity curves of gels from homo-and copolymers in aqueous medium reviewed in our previous paper were studied. Viscosity vs. rate of shear, and viscosity vs. shearing time were analysed. The viscosity curves can be described with multiplicative functions and the slope of these functions characterizes the orientation ability of polymer molecule-chains under shear. On the base of viscosity vs. shearing time functions the network formed from polymers can be classified into energetic structure, topologic one and/or friction one. It was also established, that the aqueous polymer network structures studied do not thixotropic systems.
