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]
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.
2-Ethylhexyl acrylate and butyl acrylate are the major base monomers for the preparation of acrylate adhesives. 2-Ethylhexyl acrylate can react by free-radical polymerization to form macromolecules having a molecular weight of up to 200,000 g/mol.
MMA is a raw material for the manufacture of other methacrylates. These derivatives include ethyl methacrylate (EMA), butyl methacrylate (BMA) and 2-ethyl hexyl methacrylate (2-EHMA). Methacrylic acid (MAA) is used as a chemical intermediate as well as in the manufacture of coating polymers, construction chemicals and textile applications. [15]
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]
In 1960, O. Wichterle and D. Lím [7] described its use in synthesis of hydrophilic crosslinked networks, and these results had great importance for manufacture of soft contact lenses. [5] Polyhydroxyethylmethacrylate is hydrophilic: it is capable of absorbing from 10 to 600% water relative to the dry weight.
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]
It is used as a monomer to prepare hydroxyapatite/poly methyl methacrylate composites. EGDMA can be used in free radical copolymer crosslinking reactions. Its toxicity profile has been fairly well studied. [3] It is sometimes called ethylene dimethacrylate. [4]
