    Description / Table of Contents: Abstract A series of sequential interpenetrating polymer networks, IPN's, of poly(n-butyl acrylate) and polystyrene were prepared. A new equation predicting the domain size in IPN's is summarized and shown to yield agreement with the morphologies observed via scanning electron microscopy. The experimental variables required to determine the domain size include the volume fraction and crosslink level of each polymer, the interfacial tension and the temperature.
    Notes: Résumé Un nouveau modèle thermodynamique prédisant la taille des domaines des réseaux polymères interpénétrés préparés en deux étapes est décrite. Les paramètres influents sont la tension interfaciale et la densité de réticulation des deux polymères, ainsi que la composition. A l'aide de la microscopie électronique à balayage, la théorie a été vérifiée pour le système poly(acrylate den-butyle)/polystyrène.

    Notes: An interpenetrating polymer network, IPN, is defined as a combination of two or more polymers in network form, at least one of which is polymerized and/or crosslinked in the immediate presence of the other(s). The synthesis, morphology and mechanical properties of recent works are reviewed, with special emphasis on dual phase continuity, and the number of physical entanglements that arise in homo-IPNs. The concepts of phase diagrams are applied, especially to simultaneous interpenetrating network phase separations and gelations. Recent engineering applications are discussed.
