Some dimethacrylate identifiers may have been claimed confidential, or may not have been provided, and therefore not be displayed.

Ethylene glycol dimethylacrylate EGDMA is a diester formed by condensation of two equivalents of methacrylic acid and one equivalent of ethylene glycol. EGDMA can be used in free radical copolymer crosslinking reactions. When used with methyl methacrylate , it leads to gel point at relatively low concentrations because of the nearly equivalent reactivities of all the double bonds involved. Its toxicity profile has been fairly well studied. This article about an alkene is a stub. You can help Wikipedia by expanding it. This article about an ester is a stub.

Literature data indicate that polymerization efficacy depends, among other factors, on the type of methacrylate resin comprising the material. The aim of this study was to evaluate the polymerization efficacy of four dental cement materials characterized by different polymerization mechanisms using FTIR analysis. In the present study, the FTIR method was adopted to analyze the degree of polymerization efficacy of four resin-based dental cement materials, two of which were self-cured and two were dual-cured cements. The IR spectral analysis was performed 24 h after the polymerization of the cementitious material. RelyX ARC cement exhibits the lowest polymerization efficacy

Material characterization by the determination of relationships between structure and properties at different scales is essential for contemporary material engineering. This review article provides a summary of such studies on dimethacrylate polymer networks. These polymers serve as photocuring organic matrices in the composite dental restorative materials. The polymer network structure was discussed from the perspective of the following three aspects: the chemical structure, molecular structure characterized by the degree of conversion and crosslink density chemical as well as physical , and supramolecular structure characterized by the microgel agglomerate dimensions. Instrumental techniques and methodologies currently used for the determination of particular structural parameters were summarized. The influence of those parameters as well as the role of hydrogen bonding on basic mechanical properties of dimethacrylate polymer networks were finally demonstrated. Mechanical strength, modulus of elasticity, hardness, and impact resistance were discussed. The issue of the relationship between chemical structure and water sorption was also addressed.

A recently developed successful approach to achieve the balanced properties involves the copolymerization of film forming monomers like acrylate and methacrylates with crosslinkable monomers. The crosslinker used in the copolymerization of acrylates are basically compound with at least two non-conjugated ethylenic double bonds in their molecule. The kinetics of esterification of multifunctional monomers were investigated using poly propylene glycol diacrylates.
