Acrylic acid (IUPAC: prop-2-enoic acid) is an organic compound with the formula CH 2 =CHCOOH. It is the simplest unsaturated carboxylic acid, consisting of a vinyl group connected directly to a carboxylic acid terminus. This colorless liquid has a characteristic acrid or tart smell. It is miscible with water, alcohols, ethers, and chloroform ...
Acryloyl chloride, like volatile acid chlorides, is a skin irritant, with pulmonary edema in more severe exposures. [6] Other signs and symptoms of acute exposure may include headache, dizziness, and weakness. Gastrointestinal effects may include nausea, vomiting, diarrhea, and stomach ulceration. [7]
Polyacrylic acid is a weak anionic polyelectrolyte, whose degree of ionisation is dependent on solution pH. In its non-ionised form at low pHs, PAA may associate with various non-ionic polymers (such as polyethylene oxide, poly-N-vinyl pyrrolidone, polyacrylamide, and some cellulose ethers) and form hydrogen-bonded interpolymer complexes.

Ethyl acrylate is produced by acid-catalysed esterification of acrylic acid, which in turn is produced by oxidation of propylene. It may also be prepared from acetylene, carbon monoxide and ethanol by a Reppe reaction. Commercial preparations contain a polymerization inhibitor such as hydroquinone, phenothiazine, or hydroquinone ethyl ether. [5]
Butyl acrylate is of low acute toxicity with an LD 50 (rat) of 3143 mg/kg. [4]In rodent models, butyl acrylate is metabolized by carboxylesterase or reactions with glutathione; this detoxification produces acrylic acid, butanol, and mercapturic acid waste, which are excreted.
Another method tested in a study to produce sodium polyacrylate as an alternative to current methods began with Butyl acrylate-acrylic acid copolymer and poly (butyl acrylate). [4] They were synthesized via suspension polymerization by using butyl acrylate as the main monomer and acrylic acid as a secondary monomer. Suspension polymerization ...

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 ...
