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.
Methacrylic acid, abbreviated MAA, is an organic compound with the formula CH 2 =C(CH 3)CO 2 H. This colorless, viscous liquid is a carboxylic acid with an acrid unpleasant odor.
The monomer is a viscous liquid with a pungent odour. The first polymeric form of methacrylic acid was described in 1880 by Engelhorn and Fittig. The use of high purity monomers is required for proper polymerization conditions and therefore it is necessary to remove any inhibitors by extraction (phenolic inhibitors) or via distillation. [ 2 ]
Ethyl methacrylate is the organic compound with the formula C 2 H 5 O 2 CC(CH 3)=CH 2.A colorless liquid, it is a common monomer for the preparation of acrylate polymers. [1] It is typically polymerized under free-radical conditions.
Monomer; Atom; Monomers are assigned short unique identifiers in internal HELM databases and can be represented by the identifier in strings. The approach is similar to that used in Simplified molecular-input line-entry system (SMILES). An exchangeable file format allows sharing of data between companies who have assigned different identifiers ...
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]

Fast and complete initiation of the monomer. This means that the rate at which an initiating agent activates the monomer for polymerization, must happen very quickly. How many monomers make up each polymer (the degree of polymerization) must be related linearly to the amount of monomer you started with. The dispersity of the polymer must be < 1 ...
