31. Compatibility and Thermal Studies Of Blends Of PMMA 350000 In 1,4-Dioxane By Ultrasonic Technique.

Author

Subjects
POLYMER blends, POLYMETHYLMETHACRYLATE, REFRACTIVE index, MOLECULAR interactions, VISCOMETRY
Abstract

The scientific and commercial progress in the area of polymer blends during the past two decades has been tremendous and was driven by the realization that new molecules are not always required to meet the needs of new materials and that blending can usually be implemented to meet the needs of new materials more rapidly and economically than the development of new chemistry. In the present study, activation energy of Poly(methyl methacrylate) (molar mass 350000) in 1,4-Dioxane is determined using viscometry technique. PMMA 350000 is blended with PS 35000 and the miscibility nature of the blend is analysed by ultrasonic velocity, density, viscosity and refractive index techniques at 303K. Molecular interaction properties of the blend is also discussed. [ABSTRACT FROM AUTHOR]

Abstract

Ultrasonic study has become an important research tool in the field of polymers for investigating the structure and molecular interactions in multi component system. Ultrasonic studies were carried out on Polypropylene glycol [PPG 3000] at different concentrations [0-1%] in toluene at 303K. Various parameters like adiabatic compressibility, free volume and internal pressure were calculated. The ultrasonic velocity increases with increase in the concentration. An attempt has been made to blend Polypropylene glycol [PPG] 400 with PPG 3000 at 303K at various compositions and the miscibility nature of the blend is analyzed through ultrasonic study. The variation of ultrasonic velocity with blend composition is nonlinear and follows S-type pattern, which shows that the blend is immiscible. The miscibility nature of the blend is further confirmed through other techniques like viscosity and optical studies. [ABSTRACT FROM AUTHOR]

Abstract

Ultrasonic study has become an important research tool in the field of polymers for investigating the structure and molecular interactions in multi component system. Ultrasonic studies were carried out on Polyethylene glycol (PEG 1000) at different concentrations (0-1%) in toluene at 303K. Ultrasonic parameters like adiabatic compressibility, free volume and internal pressure were calculated. The ultrasonic velocity decreases with increase in concentration. The effect of concentration is analyzed. An attempt has been made to blend PEG 1000 with PPG 1000 at 303K at various compositions 1:0, 0.8:0.2, 0.6:0.4, 0.5:0.5, 0.4:0.6, 0.2:0.8, 0:1 and the miscibility nature of the blend is analyzed through ultrasonic technique. The variation of ultrasonic velocity with blend composition is nonlinear and follows S-type pattern, which shows that the blend is immiscible. The miscibility nature of the blend is further confirmed through other techniques like viscosity and refractive index studies. [ABSTRACT FROM AUTHOR]
