Biopolymers have undergone growing development in the last twenty-five years because of their important applications in several areas of medicine. Monomers Bis-GMA and MMA are widely used in either the teeth restoration or complete substitution, respectively. This work reports the design and synthesis of allyl-3,5 bis(((allyloxy)carbonyl)oxy)benzoate (35DACBzA) and its evaluation as an eluent for Bis-GMA in dental resin composites and as a crosslinking agent for MMA. The resin formulated with monomer 35DACBzA showed polymerization shrinkage 40% lower than control. Besides, it presented a degree of conversion 27% greater, water sorption 53% lower, and solubility 80% lower than the composite resin used as control. When 35DACBzA monomer was used as MMA crosslinker, copolymer showed a thermal stability 100 degrees greater than the MMA homopolymer. This proves that monomer 35DACBzA may be used as an eluent for Bis-GMA in the formulation of dental resin composites with a high degree double bond conversion, less polymerization shrinkage, and less aqueous sorption as well as a crosslinking agent for methacrylic polymers with greater thermal stability.
