However, the higher ratio of the end-group functionalities in the branches in each prepolymer chain that cannot act as a cross-link point, combined with the lower elasticity of the shorter chains themselves lead to lower elastic networks in medium conversion ranges so that comparable mechanical properties with networks made from conventional (longer chain) resins requires reaching to very high conversions. Furthermore, since their gelation point occurs at higher conversions, the acceptable conversion range at which the properties are reached is narrower. This explains the reason behind the crucial role of controlling reaction conditions for these systems to enable reaching acceptable performance.
