| Abstract | ||
| Some physical properties of high viscosity Carboxy Methyl Cellulose dissolved in distilled water had been studied. The study includes mechanical properties by using ultrasonic wave system of frequency (40 KHz). These properties are ultrasonic velocity, ultrasonic absorption coefficient, compressibility, relaxation time, relaxation amplitude, specific acoustic impedance and bulk modulus and shear viscosity. Results show that all these properties were increasing with the increase of the ultrasonic velocity except compressibility was decreasing with the ultrasonic velocity. Results show that ultrasonic make degradation to the polymer chains, and the free radicals rebounded to make entanglement interactions which is responsible for increasing the properties. The aim of this research is to find different properties of this polymer and determine its different industrial applications according to these properties. | ||
