Термодинамика низкомолекулярного регулярно чередующегося сополимера пропилена с монооксидом углерода в области 0-350 к

The heat capacity of the biodegradable and biocompatible low-molecular alternant copolymer of propylene and carbone monoxide (polyketone) were studied in the 6?{350 K region by adiabatic vacuum calorimetry technique. The energy of combustion of the copolymer was measured calorimetrically at 298.15 K. The thermodynamic functions in the 0?{350 K region and thermodynamic characteristics of the formation of the copolymer from simple substances at T = 298.15 K and po = 0.1 MPa were calculated. The standard thermodynamic parameters of its synthesis between 0?{350 K were calculated. The results obtained were compared with similar ones for high-molecular alternant copolymer of propylene and carbone monoxide and for highand low-molecular alternant copolymer of ethylene and carbone monoxide.
