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.
3-Methoxy-4-methylamphetamine (MMA) is an entactogen and psychedelic drug of the phenethylamine and amphetamine classes. [ 1 ] [ 2 ] It was first synthesized in 1970 [ 1 ] and was encountered as a street drug in Italy in the same decade. [ 3 ]
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]
It is a common monomer used in the production of epoxy resins. While typical home epoxies contain diglycidyl ether of bisphenol A (DGEBA), glycidyl methacrylate is instead used to provide epoxy functionalization to polyolefins and other acrylate resins. Glycidyl methacrylate is produced by several companies worldwide, including Dow Chemical. [2]
Garcia was then scheduled to make her MMA debut with Jungle Fight in March 2015. [23] However, this bout also didn't happen. On November 6, 2015, it was announced during Bellator 145 that Garcia would face Lei'D Tapa for Rizin Fighting Federation on December 31, 2015. [24] Garcia won the fight via TKO in the first round.

The recovered monomers then are purified, but the costs and complexity have prevented this from becoming the norm. [30] Another approach binds monomers to the ends of long polymer chains. Those monomers detach when heated, triggering the chain to disassemble, with monomer yields of up to 90%, although the presence of dyes reduce this number.
