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.
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.

Acrylates (IUPAC: prop-2-enoates) are the salts, esters, and conjugate bases of acrylic acid. The acrylate ion is the anion CH 2 =CHCO − 2. Often, acrylate refers to esters of acrylic acid, the most common member being methyl acrylate. These acrylates contain vinyl groups.
An α,β-unsaturated acid is a type of α,β-unsaturated carbonyl compound that consists of an alkene conjugated to a carboxylic acid. [3] The simplest example is acrylic acid (CH 2 =CHCO 2 H). These compounds are prone to polymerization, giving rise to the large area of polyacrylate plastics.
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 ...
Methyl acrylate is an organic compound, more accurately the methyl ester of acrylic acid. It is a colourless liquid with a characteristic acrid odor. It is mainly produced to make acrylate fiber, which is used to weave synthetic carpets. [6] It is also a reagent in the synthesis of various pharmaceutical intermediates.
