METHOD OF DETERMINATION OF HEAT CAPACITY OF POLYMERS AT CONSTANT PRESSURE

摘要

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
