Tertiary aromatic amines were synthesized with various nitrogen and ring substituents. They were compared with commercial homologues using composites based on dimethacrylate monomer formulations containing benzoyl peroxide. Equimolar amounts of the different amines were the only variables. Although accelerating ability was a function of both ring and nitrogen substitution, color stability was influenced more by the substituents on the ring than by the substituents on the nitrogen
