Ethyl cyanoacrylate (ECA), a cyanoacrylate ester, is an ethyl ester of 2-cyano-acrylic acid. It is a colorless liquid with low viscosity and a faint sweet smell in pure form. It is the main component of cyanoacrylate glues and can be encountered under many trade names . [ 2 ]
Cyanoacrylate glue is widely used in human and veterinary medicine. [6] It was in veterinary use for mending bone, hide, and tortoise shell by the early 1970s or before. A cyanoacrylate spray was used in the Vietnam War to reduce bleeding in wounded soldiers until they could be taken to a hospital. [7]
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 ...
Acrylic elastomer is a general term for a type of synthetic rubber whose primary component is acrylic acid alkyl ester (ethyl or butyl ester). [3] Acrylic elastomer possesses characteristics of heat and oil resistance, with the ability to withstand temperatures of 170–180 °C. It is used primarily for producing oil seals and packaging related ...
Ethyl acrylate reacts with amines catalyzed by Lewis acids in a Michael addition to β-alanine derivatives in high yields: [13]. The nucleophilic addition at ethyl acrylate as an α,β-unsaturated carbonyl compound is a frequent strategy in the synthesis of pharmaceutical intermediates.
Poly(ethyl acrylate) (PEA) is a family of organic polymers with the formula (CH 2 CHCO 2 CH 2 CH 3) n. It is a synthetic acrylate polymer derived from ethyl acrylate monomer. The polymers are colorless. This homopolymer is far less important than copolymers derived from ethyl acrylate and other monomers.
An acrylic resin is a thermoplastic or thermosetting plastic substance typically derived from acrylic acid, methacrylic acid and acrylate monomers such as butyl acrylate and methacrylate monomers such as methyl methacrylate. Thermoplastic acrylics designate a group of acrylic resins typically containing both a high molecular weight and a high ...
Monomers activated by strong electronegative groups may be initiated even by weak anionic or neutral nucleophiles (i.e. amines, phosphines). Most prominent example is the curing of cyanoacrylate, which constitutes the basis for superglue.
