2. Methyl methacrylate - Wikipedia

   en.wikipedia.org/wiki/Methyl_methacrylate

   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.

3. Polymerisation inhibitor - Wikipedia

   en.wikipedia.org/wiki/Polymerisation_inhibitor

   Purified monomers stored at ambient temperatures are of less risk of polymerising and as such the most highly reactive inhibitors are rarely used at this stage. In general compounds are chosen which can be easily removed immediately prior to industrial polymerisation to make plastics.

4. Methacrylic acid - Wikipedia

   en.wikipedia.org/wiki/Methacrylic_acid

   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.

5. Poly (methacrylic acid) - Wikipedia

   en.wikipedia.org/wiki/Poly(methacrylic_acid)

   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 ]

7. Poly(methyl methacrylate) - Wikipedia

   en.wikipedia.org/wiki/Poly(methyl_methacrylate)

   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.

8. Suspension polymerization - Wikipedia

   en.wikipedia.org/wiki/Suspension_polymerization

   In polymer chemistry, suspension polymerization is a heterogeneous radical polymerization process that uses mechanical agitation to mix a monomer or mixture of monomers in a liquid phase, such as water, while the monomers polymerize, forming spheres of polymer. [2] The monomer droplets (size of the order 10-1000 μm) are suspended in the liquid ...

9. 3-Methoxy-4-methylamphetamine - Wikipedia

   en.wikipedia.org/wiki/3-Methoxy-4-methylamphetamine

   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 ]
