摘      要：An automated system was designed to study in a continuous regime the rheological properties of the care polymeric compositions using the damped vibration *** a parallel mode measurements of rheological and acoustic characteristics of the care compositions were made on the basis of epoxy *** of shear modulus,viscosity,the sound speed,and the damping coefficient as functions of polymerization were *** of spectral characteristics of acoustic signals in the polymerization were *** of the experimental results obtained reveals that the dynamics of the variation of acoustic and rheological properties is significantly *** major change of acoustic characteristics occurs in the initial stage of the solid state formation when a transition from a liquid-to-gel like state takes *** characteristics vary dramatically at the crossover from a high-viscosity to solid *** the frequency dependencies of an acoustic signal a number of essential features were observed.
