EDMA

EDMA (Ethylene Dimethacrylate) is a chemical compound commonly used in various industrial and medical applications. It is a type of dimethacrylate ester, which is a derivative of methacrylic acid. EDMA is known for its role as a cross-linking agent in the production of polymers and resins.

Chemical Properties

EDMA has the chemical formula C10H14O4 and a molecular weight of 198.22 g/mol. It is a colorless liquid with a characteristic odor. The compound is soluble in organic solvents such as ethanol, acetone, and benzene, but it is insoluble in water.

Synthesis

EDMA is synthesized through the esterification of ethylene glycol with methacrylic acid. The reaction typically involves the use of a catalyst such as sulfuric acid to facilitate the process.

Applications

Polymer Production

EDMA is widely used in the production of polymers and resins. It acts as a cross-linking agent, which helps in forming three-dimensional networks in polymer structures. This property is particularly useful in the manufacturing of dental materials, adhesives, and coatings.

Medical Applications

In the medical field, EDMA is used in the formulation of dental composites and bone cements. Its ability to enhance the mechanical properties of these materials makes it a valuable component in dental restorations and orthopedic surgeries.

Other Uses

EDMA is also employed in the production of contact lenses, optical fibers, and photopolymer plates. Its versatility and effectiveness as a cross-linking agent make it a popular choice in various industrial applications.

Safety and Handling

EDMA should be handled with care, as it can cause skin and eye irritation. Proper personal protective equipment (PPE) such as gloves and goggles should be worn when handling the compound. In case of contact with skin or eyes, the affected area should be rinsed thoroughly with water.
