XLD was calculated by counting the number of HMMM molecules connected to at least three different acrylic chains and dividing this by the system's volume. As shown in Figure , XLD slightly increases with decreasing chain length but rises significantly with increasing functionality, as the number of loops reduces, which allows more cross-linkers to attach to different chains. Higher prepolymer functionality results in a greater concentration of HMMM per unit volume, due to the constant melamine/acrylic functional group ratio across all systems. This leads to a higher XLD in systems with greater functionality. In polymer networks with similar chemistry but varying numbers of connectivity, the network topology typically explains differences in thermal and mechanical behavior at First, our cross-linked networks have a variety of connection sites, each is connected to between one and six different chains. By assigning weights to these connection points, their contribution to adding elasticity to the network is taken into account, which addresses the diversity in the functionality of network constitutes.
