ABSTRACT
This chapter deals with the preparation and characterization of nanostructured thermosetting materials based on unsaturated polyester modified with different block copolymers. Immiscible block of block copolymers microphase separated from the unsaturated polyester matrices leading to nanostructured thermosetting materials with ability to act as template for inorganic and organic nanoentities. The effect of miscibility, crystallinity and morphology on the final properties such as optical and mechanical is also discussed.
