A colorless liquid, it is a common monomer for the preparation of acrylate polymers. [1] It is typically polymerized under free-radical conditions. [2] Ethyl methacrylate was first obtained by treating ethyl 2-hydroxyisobutyrate with phosphorus pentachloride in a dehydration reaction. [3]

Many monomers are purified industrially by distillation, which can lead to thermally-initiated polymerisation. Styrene, for example, is distilled at temperatures above 100 °C whereupon it undergoes thermal polymerisation at a rate of ~2% per hour. [ 1 ]
Poly(ethyl methacrylate) (PEMA) is a hydrophobic synthetic acrylate polymer.It has properties similar to the more common PMMA, however it produces less heat during polymerization, has a lower modulus of elasticity and has an overall softer texture. [7]
Use of MMA (Methyl methacrylate liquid monomers) acrylics are strongly discouraged and banned in some states as it can cause damage to the natural nail, asthma; irritated eyes, skin, nose, and mouth; difficulty concentrating; loss of smell and kidney issues. [4] A suitable alternative is EMA (Ethyl Methacrylate Liquid Monomers) in salon use.
A colorless or white solid, it is a monomer for the production of polymers and copolymers, some of which are used in hydrogels. [2] Methacrylamide is also a precursor of methyl methacrylate . References
An acrylate polymer (also known as acrylic or polyacrylate) is any of a group of polymers prepared from acrylate monomers. These plastics are noted for their transparency, resistance to breakage, and elasticity. Acrylate polymer is commonly used in cosmetics, such as nail polish, as an adhesive. [1]
Hydroxyethylmethacrylate was first synthesized around 1925. Common methods of synthesis are: [5] reaction of methacrylic acid with ethylene oxide;; esterification of methacrylic acid with a large excess of ethylene glycol.
