Thermal, mechanical and morphological measurements of reactive thermop
lastic modified epoxy resin are reported. Phase separation occurs duri
ng the curing. To a small decrease of the modulus of the final materia
ls a large increase of the toughness of the thermoset is associated, a
s compared with the neat epoxy resin when cured with an usual curing a
