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 ).
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. [15]
Poly(methyl acrylate) is a tacky material near room temperature, and as such it is not particularly useful as a structural material. Commonly, methyl acrylate (and other acrylate esters) are copolymerized with other alkenes to give useful engineering plastics. [17] A variety of vinyl monomers are used, including styrene and other acrylates. [18]
Poly(methyl acrylate) (PMA) is a family of organic polymers with the formula (CH 2 CHCO 2 CH 3) n. It is a synthetic acrylate polymer derived from methyl acrylate monomer. The polymers are colorless.
Poly(ethyl methacrylate) (PEMA) is a hydrophobic synthetic acrylate polymer. It has properties similar to the more common PMMA, however it produces less heat during polymerization, has a lower modulus of elasticity and has an overall softer texture. [7] It may be vulcanized using lead oxide as a catalyst [8] and it can be softened using ethanol.
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.
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.
