Methyl cyanoacrylate (MCA; also sometimes referred to as α-cyanoacrylate or alpha-cyanoacrylate) [3] is an organic compound that contains several functional groups: a methyl ester, a nitrile, and an alkene. It is a colorless liquid with low viscosity. Its chief use is as the main component of cyanoacrylate glues.
Structure of the backbone of a cyanoacrylate polymer. In the same way that several variants of acrylic esters are known, so too are the corresponding polymers. Their properties strongly depends on the substituent. A large family of acrylate-like polymers are derived from methyl methacrylate and many related esters, especially polymethyl ...
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]
The compound 2-octyl cyanoacrylate degrades much more slowly due to its longer organic backbone (series of covalently bonded carbon molecules) and the adhesive does not reach the threshold of tissue toxicity. Due to the toxicity issues of ethyl cyanoacrylate, the use of 2-octyl cyanoacrylate for sutures is preferred. [33]
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.
"Super glue" is a formulation of cyanoacrylate. 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.
Poly(methyl methacrylate) (PMMA) is the synthetic polymer derived from methyl methacrylate. It is used as an engineering plastic , and it is a transparent thermoplastic . 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 ...
