Description / Table of Contents:
Die Verbrennungsenthalpie von dem aus endo-2-Methyl-7-oxabicyclo[2.2.1]heptan hergestellten Poly(oxy-2-methyl-1,4-cyclohexenylen)wurde kalorimetrisch unter Verwendung einer Verbrennungsbombe bestimmt. Aus der so bestimmten Standard-Bildungsenthalpie des Polymers, ΔH0f (298, 15 K)= - 283,5±3,0kJ (Grund-mol) - 1 und der des Monomers wurde die Polymerisationsenthalpie (flüssiges Monomer→festes Polymer) zu ΔH01c = - 33,3±3,7kJ mol - 1 berechnet.
Notes:
The enthalpy of combustion of poly(oxy-2-methyl-1,4-cyclohexenylene) prepared from endo-2-methyl-7-oxabicyclo[2.2.1]heptane has been determined by oxygen-bomb combustion calorimetry. The calculated standard enthalpy of formation of the polymer, ΔH0f (298,15K)= - 283,5±3,0 kJ (base-mol) - 1, has been combined with that of the monomer to give the enthalpy of polymerisation of liquid monomer to solid polymer as ΔH0ic = - 33,3±3,7 kJ mol - 1.
