Abstract

The rheology of the epoxy/block copolymer blends is an important learning tool to understand the microphase separation of one of the blocks of block copolymer during the curing process. The knowledge about the viscoelastic changes during the thermosetting network formation allows to better understand the processes such as gelation, vitrification, and microphase separation. Different methods can be employed to determine the gelation point of the epoxy/block copolymer blends. The first method is related to the extrapolation of the complex viscosity (η*) to infinite, the second to the intersection of dynamic storage modulus (G′) and dynamic loss modulus (G″) curves, and the third one to the fact that tan δ is independent on frequency at gelation point. In this chapter, a few examples of rheology of epoxy/block copolymer blends will be presented with the main aim of showing the correlation between rheological behavior and final properties of thermosetting systems.
