Abstract
The heat capacity of a partially crystalline second-generation poly(phenylene-pyridyl) dendron with a dodecyl-decorated periphery is studied by high-precision adiabatic vacuum and differential scanning calorimetry in the temperature range of 6 to 530 K. The thermodynamic characteristics of the glass’s transition and melting are determined from the calorimetric data and the degree of its crystallinity is estimated (α = 30%). Standard thermodynamic functions (Cp°, H°-H°(0), S°-S°(0), and G°-H°(0)) for a partially crystalline dendron in the range of T → 0 to 480 K are calculated.
