2.3 Poly(methyl methacrylate) [9011-14-7
vtechworks.lib.vt.edu2.3.1 Polymerization of Methyl Methacrylate [80-62-6] PMMA can be produced using a variety of polymerization mechanisms. The most common technique is the free radical polymerization of MMA. The free radical polymerization of acrylates and methacrylates is a chain polymerization across the double bond of the monomer (Figure 2.5).

www.aqmd.govMethyl Methacrylate (MMA) is sometimes present as a secondary monomer added to the gel coat formulation to increase the UV-resistance, to improve the surface finish, and to impart greater toughness. The greater vapor pressure of MMA makes it much more volatile than styrene. Its emissions must be estimated separately from styrene emissions.
