Étude ultrasonore de mélanges de polymères

Evaluation of new conducting polymeric membrane based on sulfonation of compatibilized NR/EPDM blend

“…Ultrasonic velocity measurements have been reported [15][16][17][18][19][20][21][22] as a precise technique to investigate the degree of compatibility in highly viscous or solid forms of polymer blends. A new approach to study the polymer blend compatibility with ultrasonic attenuation was also reported by Arman 23 and Belaribi et al 24 They reported poor adhesion between two polymers leading to high values of the attenuation coefficient. Singh et al [16][17][18][19] studied the ultrasonic velocity for compatible, semicompatible, and incompatible polymeric blends, and they found that in compatible blends, the ultrasonic velocity varied linearly to its composition.…”

Evaluation of the Effect of Polymeric Compounds as Compatibilizers for NR/EPDM Blend

“…Ultrasonic velocity measurements have been reported [8][9][10][11][12][13][14][15] as a precise technique to investigate the degree of compatibility in highly viscous or solid forms of polymer blends. A new approach to the study of polymer blend compatibility with ultrasonic attenuation was reported by Armen et al, Belaribi et al, and Shehata and Amer [16][17][18] . They reported poor adhesion between two polymers leading to high values of the attenuation coefficient.…”

Ultrasonic studies on polystyrene/styrene butadiene rubber polymer blends filled with glass fiber and talc

“…Many experimental and theoretical studies reported in this field, extensive work has been recently carried out using the compositional dependence of the compressional ultrasonic wave velocities and its attenuation in solution and solid polymer blends [1][2][3][4][5][6][7][8][9][10][11]. They concluded that in compatible blends the ultrasonic velocity varies linearly with composition while it deviates from linearity in incompatible polymer blends.…”
