The thermodynamic properties of carbosilane dendrimer of second generation with terminal methoxyundecylene groups were studied
between 6 and 340 K by adiabatic vacuum calorimetry: the temperature dependence of the molar heat capacity Cp0 was measured, the physical transformations were established and their thermodynamic characteristics were obtained. The experimental
data were used to calculate the thermodynamic functions Cp0 (T), H0(T)-H0(0), S0(T), G0(T)-H0(0) of the compound in the range 0 to 340 K. from the relation Cp0 (T) the fractal dimension of the dendrimer was experimentally determined. The heat capacity of the dendrimer was compared with
the corresponding additive values calculated from the properties of its constituents - a dendritic matrix (carbosilane dendrimer
of second generation) and the corresponding amount of moles of methyl ester of 11-(tetramethyldisiloxy)undecanoic acid serving
as terminal groups.
