Abstract Based on the phenomenon of freezing point depression of a solvent byΔT, experimental evidence is presented to show that the distance between the junction points can be calculated fromΔT. Direct measurements of the temperature-time-curve of the cooling network and the Differential Scanning Calorimetry offer the determination ofΔT. Except the mean distances ¯d c in dependence on cross-linking density, swelling degree, and other network parameters, the distribution of the distance between the junction pointsH(dc) can be determined, which allows conclusions on the course of cross-linking reaction. This paper attempts to give experimental evidence of influences of the breadth ofH(dc) on application-relevant properties.
