An azo prepolymer (TAZ) was synthesized by reaction between Disperse Orange 3 (DO3) and diglycidyl ether of bisphenol A (DGEBA). The resulting TAZ was blended with DGEBA and different amines (mono and diamines) in order to obtain linear and crosslinked polymers. The influence of crosslinking over optical properties has been analyzed and the results compared to the behavior observed in thermoplastic epoxies
