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]
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]
In polymer chemistry, polymerisation inhibitors (US: polymerization inhibitors) are chemical compounds added to monomers to prevent their self-polymerisation. Unsaturated monomers such as acrylates, vinyl chloride, butadiene and styrene require inhibitors for both processing and safe transport and storage.
Hydroxyethylmethacrylate is a monomer that is used to make various polymers. Synthesis. Hydroxyethylmethacrylate was first synthesized around 1925.
In the US market, soft contact lenses are approved by the US Food and Drug Administration. [2] The American Optometric Association published a contact lens comparison chart called Advantages and Disadvantages of Various Types of Contact Lenses on the differences between them. [3]
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.

Epoxide monomers may be cross linked with themselves, or with the addition of a co-reactant, to form epoxy; BPA is the monomer precursor for polycarbonate; Terephthalic acid is a comonomer that, with ethylene glycol, forms polyethylene terephthalate. Dimethylsilicon dichloride is a monomer that, upon hydrolysis, gives polydimethylsiloxane.
