Boiling Point: 189°C.
Flash Point: 85°C.
Refractive Index: 1.4473. It is soluble in common organic solvents and insoluble in water.
Chemical Properties
Reactions of Acrylate Double Bonds: The acrylate double bonds in GMA are highly reactive. They can undergo self - polymerization reactions to form polyglycidyl methacrylate (PGMA). Additionally, they can copolymerize with monomers such as styrene, acrylates, and vinyl monomers to introduce epoxy functional groups into the polymer chain, endowing the material with cross - linking, adhesion, or other reactive properties.
Reactions of Epoxy Groups: The epoxy groups in GMA can react with nucleophiles such as amines, carboxylic acids, and thiols. Under acidic conditions, they can react with alcohols or phenols to form ether bonds; under alkaline conditions, they can react with carboxylic acids to form ester bonds. These reactions are often used to introduce functional groups or achieve cross - linking.
Hydrolysis and Stability: GMA may undergo slow hydrolysis when exposed to water or strong acids and bases for a long time, and the epoxy ring opens to form a diol structure. Therefore, it should be stored in a dry environment. At high temperatures (above 100°C), it may undergo self - polymerization, so inhibitors such as hydroquinone are usually added.
Applications
Coatings and Adhesives: In coatings, GMA can be used to prepare epoxy - modified acrylic coatings, which can improve the hardness, gloss, adhesion, and weather resistance of the coating film. In adhesives, especially in UV - curable adhesives, GMA, together with photoinitiators, is used for the encapsulation of electronic components or the bonding of optical materials. The cross - linking of epoxy groups can improve the bonding strength.
Polymer Modification: GMA is used as a compatibilizer in polymer blends. For example, in the PE/PA blend system, GMA can improve the compatibility between the two polymers through the reaction of its epoxy groups with the functional groups on the polymer surface, thereby enhancing the mechanical properties of the blend material.
Other Fields: GMA is also widely used in the preparation of ion - exchange resins, chelating resins, medical selective filtration membranes, anti - coagulants, dental materials, and non - soluble adsorbents.
