Глицидилметакрилат химические свойства, назначение, производство
Описание
Glycidyl Methacrylate (GMA) is a clear, colorless liquid with a potent ester and fruity odor. It comprises a polymerizable methacrylate functional group on one end and a reactive epoxy group on the other. It is slightly miscible with water, soluble in most organic solvents, and has relatively low volatility. Its vapor is heavier than air. It copolymerizes readily with various functional groups, such as phenols, ketones, acids, and amines. The added epoxy group imparts durability, mechanical strength, optical transparency, and adhesiveness.
Химические свойства
Glycidyl methacrylate (GMA) is a colorless liquid with a fruity odor. Floats on water. (USCG, 1999)
Glycidyl methacrylate is a polyfunctional monomer. It acts as an adhesion promoting crosslinking co-monomer for acrylic and vinyl resins. It is also a reactive colorless diluent. GMA is soluble in ethanol, acetone, diethyl ether, benzene.
Использование
Glycidyl methacrylate (GMA) is a common monomer used in the creation of epoxy resins. It is used to provide epoxy functionalization to polyolefins and other acrylate resins.
Glycidyl methacrylate is used in the production of polymer coatings and finishes, adhesives, plastics and elastomers.
Glycidyl methacrylate dextran has been reported to be used as a biocompatible hydrogel. In situ polymerization of GMA with trimethylolpropane trimethacrylate to form macroporous sorbents has also been reported. GMA may also be grafted onto polypropylene.
Подготовка
Glycidyl methacrylate is produced from methacrylic acid and glycidol. Glycidol contain both epoxide and alcohol functional groups.It is an enoate ester and an epoxide. It derives from a methacrylic acid and a glycidol.
Реакции
Glycidyl methacrylate (GMA) is a kind of functional monomer. Its active vinyl and epoxy groups could be grafted with polyolefin and reacted with the polar groups such as amine, hydroxyl and carboxyl group, respectively. It can also undergo polymerization to form poly (glycidyl methacrylate).
Общее описание
Colorless liquid with a fruity odor. Floats on water.
Реакции воздуха и воды
Flammable. Slightly water soluble.
Профиль реактивности
Epoxides, such as Glycidyl methacrylate, are highly reactive. They polymerize in the presence of catalysts or when heated. These polymerization reactions can be violent. Compounds in this group react with acids, bases, and oxidizing and reducing agents. They react, possibly violently with water in the presence of acid and other catalysts.
Угроза здоровью
The liquid irritates eyes about as much as soap. Prolonged contact with skin produces irritation and dermatitis.
Пожароопасность
