THERMODYNAMICS OF ALTERNATING COPOLYMER OF ETHYLENE AND CARBON-MONOXIDE IN THE 0-600 K REGION

The temperature dependence of the heat capacity of the alternating cop olymer (ACP) of carbon monoxide with ethylene was studied, and tempera tures and enthalpies of its phase transformations were measured by adi abatic vacuum, dynamic, and isothermal calorimetry in the temperature range from 8 to 600 K. The energy of burning of ACP was measured at 29 8.15 K in a calorimeter with the static bomb and isothermal shell. The thermodynamic parameters of transformation of the alpha-form of ACP c rystals into the beta-form and fusion of the beta-form were determined . The thermodynamic functions for the 0-507 K range and thermodynamic characteristics at T = 298.15 K and p = 101.325 kPa were calculated. T he thermodynamic parameters of the alternating copolymerization of eth ylene and CO at 0-507 K and standard pressure were calculated for the bulk reaction.
