Polymeric Solutions

A polymer blends (PVA/PEG) have been prepared at various concentrations(6%, 8%, 10%, 12%, and 14%) g /ml by dissolving different weights from the powders{Pva and Peg}.The behavior of this mixture has been studied utilize some physical properties such as ultrasonic absorption coefficient, relaxation amplitude, specific acoustic Impedance, compression, bulk modulus, shear viscosity, and Reduced viscosity. The outcomes referenced that each of these characteristics increased with increasing concentration of polymeric solutions, "while compressibility decreased with increasing concentration solutions".
