    • In some formulations, epoxy – amine reactions or epoxy – phenol reactions are accelerated by the addition of a Lewis acid (typically a BF 3 - amine complex) or a Lewis base (often a tertiary amine or an imidazole), … 展开

    General Considerations

    As discussed in the previous section, typical epoxy monomers used to generate a polymer network have two or … 展开

    Gelation

    Gelation is a critical transition that takes place during the formation of the polymer network and corresponds to the generation of a giant macromolecular structure that percolates the reaction medium. Macroscopically … 展开

    Vitrifi cation

    During polymerization of an epoxy formulation vitrifi cation may occur if the glass transition temperature of the system, T g , equals and becomes higher than the reaction temperature, T . The condition T g ≥ T , can be achi… 展开

    Reaction - Induced Phase Separation

    Many epoxy formulations include a particular modifi er, such as a rubber, a ther-moplastic, a liquid crystal, a foaming agent, and so on, that is miscible before reaction but becomes phase separated in the course of pol… 展开
