Abstract:
The aim of this research is to improve the flow properties of polymers,
in particular viscosity, by mixing polymers to be used in various fields.
Samples prepared by stirring polyvinyl alcohol on fire for half a second
in a fixed weight ratio with divergent weight ratios of polyethylene
glycol and polyvinylpyrrolidone, both separately. Other samples were
prepared in the same way by mixing the three polymers followed by
measuring the molecular weight of all the samples. This method of
preparation made the polymers insoluble in water, therefore nitric acid
was used to dissolve them. Flow time of the solvent and all solutions
were measured, which was used to calculate the viscosities, It has been
shown that these viscosities increase with increasing concentrations of
polymers in solutions by establishing a positive relationship between
them, It was found that the intrinsic viscosity decreases with increasing
concentrations after being graphed using intrinsic viscosity calculations
from the relationship between specific viscosity and relative viscosity
logogram with concentration. These results may be used in industrial
medical applications as well as scientific studies.
