title: The monomeric formulation optimization of dental composite: mechanical and kinetic studies.
abstract: The optimization of the monomer composition, using a polymerization kinetic study and the mechanical behavior study of the composites, was the principal objective of this work. The monomeric mixture analyzed is a part of the composite that has been in development at the University of Campinas, Brazil. Parameters such as initiator, accelerator, and macro-components composition were optimized. The infrared spectroscopy was the analytical technique used in the kinetic study. On the mechanical characterization, the stress strain, flexure stress and its modulus, were the properties analyzed. The dependency between the polymeric reaction and the physical behavior of the composites and the monomer composition was observed and studied. Finally, the monomer optimum composition was determined.
