    Abstract:

    In this work we present experimental results of phase separation of an epoxy resin modified with elastomers and of full IPNs formed by blends of epoxy resin with unsaturated polyester. The elastomeric modifiers used change the reaction kinetics because they dissolve the plasticizer of the hardener, accelerating the curing reaction and increasing the glass transition temperature of the epoxy resin. The IPNs show only one glass transition when they are not cured. However, some compositions exhibit two or more transition regions when they are fully cured.
