• General Description: 1,3-Bis[2-(3,4-epoxycyclohexyl)ethyl]tetramethyldisiloxane is a siloxane-oxirane monomer with favorable rheological and physical properties, including low viscosity and suitable refractive index, making it a promising candidate for dental applications. Its synthesis was confirmed via NMR, and its photocuring potential was demonstrated with improved conversion rates when combined with additives like 1,2-ethanediol. The monomer's epoxy groups enable cationic ring-opening polymerization, which can be modulated by supramolecular proton complexes for controlled reaction kinetics. 1,3 BIS[2(3,4 EPOXYCYCLOHEX-1-YL)ETHYL]TETRA-METHYLDISILOXANE exhibits autoaccelerated polymerization behavior, suggesting utility in high-performance dental materials.
