A large family of acrylate-like polymers are derived from methyl methacrylate and many related esters, especially polymethyl methacrylate. A second large family of acrylate-like polymers are derived from ethyl cyanoacrylate , which gives rise to cyanoacrylates .
The principal application, consuming approximately 75% of the MMA, is the manufacture of polymethyl methacrylate acrylic plastics . Methyl methacrylate is also used for the production of the co-polymer methyl methacrylate-butadiene-styrene (MBS), used as a modifier for PVC.
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.
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 ).
Polymethyl methacrylate is the clear break-resistant sheeting sold as acrylic glass (or simply acrylic sheet) or under the trade name Plexiglas, Perspex, etc. Polyacrylates are used in cosmetic products as rheology modifiers and film formers, and these are typically polymers of acrylic acid fluids.

This derivative in turn is hydrolyzed to methacrylic acid, or esterified to methyl methacrylate in one step. Another route to methacrylic acid starts with isobutylene, which obtainable by dehydration of tert-butanol. Isobutylene is oxidized sequentially to methacrolein and then methacrylic acid.
