Description

Application

• The effect of 4, 4′-bis (N, N-diethylamino) benzophenone on the degree of conversion in liquid photopolymer for dental 3D printing: Examines its use as a co-initiator in dental 3D printing materials (DH Lee et al., 2015).
• Ketone Number and Substitution Effect of Benzophenone Derivatives on the Free Radical Photopolymerization: Compares its performance with other photoinitiators in polymerization (TL Huang, YC Chen, 2021).
