2-Ethylhexyl methacrylate Usage And Synthesis

Description

2-Ethylhexyl methacrylate is an ester of Methacrylic acid used as a raw material component in synthesizing polymers. It is a monofunctional monomer consisting of a methacrylate group with a characteristic high reactivity and a cyclic hydrophobic group and could form homopolymers and copolymers. 2-Ethylhexyl methacrylate could be used as a monomer for polymers in latex paints, lacquers, polishes, coating resins for food contact, and viscosity index improvers.

Chemical Properties

colourless liquid.
2-Ethylhexyl Methacrylate (2-EHMA) forms homopolymers and copolymers. Copolymers of 2-EHMA can be prepared with (meth)acrylic acid and its salts, amides, and esters and with (meth)acrylates, acrylonitrile, maleic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, unsaturated polyesters, and drying oils, etc. It is a monofunctional monomer consisting of a methacrylate group with a characteristic high reactivity and a cyclic branched hydrophobic group. It is stable but may polymerize upon exposure to light. It’s stabilized with hydroquinone monomethyl ether. 2-EHMA is heat sensitive and incompatible with strong acids, strong oxidizing agents, and strong bases.

Uses

2-Ethylhexyl Methacrylate(2-EHMA) can be used as a release coating composition,it is also used in Coating resins, Plastic improvers, Reactive Systems, Textile treating agents, Fabric auxiliary, Paper and water, Lubricating oil additives, Adhesives, and also Dental materials.

Toxicity evaluation

Virtually nontoxic after a single ingestion. Experimental/calculated data:LD50 rat (oral): >2.000 mg/kg (OECD Guideline 401).
