Resumo
It is demonstrated that by analyzing the instantaneous spectrum of an ultrasonic signal transmitted in the shadow mode through the product under study, it is possible to determine the degree of difference in the structure of products made of finely dispersed polymer materials with different contents of one of the polymer components. This cannot be achieved with traditional methods of ultrasonic structuroscopy, based on analyzing the degree of attenuation and measuring the velocity of ultrasound in the material.
