Polymer blends of unsaturated polyetherester resins and dicyclopentadiene polyester resins give single-phase, cured thermosets having high tensile and flexural strength. The thermosets exhibit a single glass- transition temperature within the range of about 70°C to about 150°C. The synergism resulting from polymer blending provides a cost-effective way to improve the strength properties of cured polyetherester thermosets, and coincidentally, gives a way to improve the flexibility and toughness of cured DCPD polyester thermosets. Glass-reinforced thermosets made from polyetherester resin blends show exceptional structural fatigue resistance.
