Poly(methyl methacrylate) (PMMA) is a synthetic polymer derived from methyl methacrylate. It is a transparent thermoplastic , used as an engineering plastic . PMMA is also known as acrylic , acrylic glass , as well as by the trade names and brands Crylux , Hesalite , Plexiglas , Acrylite , Lucite , and Perspex , among several others ( see below ).
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. It is soluble in warm water and miscible with most organic solvents.
Methyl acrylate can be prepared by debromination of methyl 2,3-dibromopropanoate with zinc. [10] Methyl acrylate is formed in good yield on pyrolysis of methyl lactate in the presence of ethenone (ketene). [11] Methyl lactate is a renewable "green chemical". Another patent [12] describes the dehydration of methyl lactate over zeolites.

Often, acrylate refers to esters of acrylic acid, the most common member being methyl acrylate. These acrylates contain vinyl groups . These compounds are of interest because they are bifunctional : the vinyl group is susceptible to polymerization and the carboxylate group carries myriad functionalities.

PMAA can act as a polyelectrolyte and has the ability to absorb and retain water. These properties are strongly affected by the pH and therefore many hydrogels are composed of PMAA copolymers. [ 3 ] [ 4 ] These hydrogel capsules can act as carrier vessels for confined drugs and act as microreactor reservoirs. [ 5 ]
