METHOD OF DETERMINATION OF HEAT CAPACITY OF POLYMERS AT CONSTANT PRESSURE Russian patent published in 2002 - IPC

Abstract RU 2181200 C2

FIELD: measurement technology. SUBSTANCE: specimen is placed in primary transducer located in microcalorimeter and mean-square value of voltage of electrical fluctuations, dielectric constant and coefficient of dielectric losses due to internal electromagnetic field are measured for two moments of heating time and special heat capacity of polymer at constant pressure is calculated. EFFECT: enhanced accuracy of measurements. 1 dwg
