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 ]
A colorless liquid, it is a common monomer for the preparation of methacrylate polymers. [1] It is typically polymerized under free-radical conditions. [2] Health hazards
Monomer to RAFT reagent: gives the expected degree of polymerization (that is, the number of monomer units in each polymer chain) and can be used to estimate the molecular weight of the polymer by Equation (1) (see below). [12] [14] RAFT reagent to initiator: determines the end groups on the polymer chains.
The Food and Drug Administration (FDA) considers American cheese to be “pasteurized process cheese.” All cheese—real or not—undergoes some degree of processing to achieve the final product.
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]
