Dimethacrylate

Some substance identifiers may have been claimed confidential, dimethacrylate, or may not have been provided, and therefore not be displayed. More information about the EC Inventory can be found here, dimethacrylate. If the substance was not covered by the EC Inventory, ECHA attributes a list number in the dimethacrylate format, starting with the numbers 6, 7, dimethacrylate, 8 or 9. The molecular formula identifies each type dimethacrylate element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance.

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 Polymerization efficacy largely depends on the chemical structure of the material in terms of the presence of a particular methacrylate resin and less on the polymerization mechanism itself, i. In clinical practice, dental cement materials are primarily used for permanent and temporary fixation of indirect restorations to natural teeth [ 1 , 2 ]. According to the setting mechanism, dental cements are divided into water-based dental cements zinc phosphate, zinc polycarboxylate and glass ionomer cements and resin-based dental cements composite cements [ 3 ].

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.
