Acrylate is a term that can refer to a salt or ester of acrylic acid. Acrylic acid itself is an organic compound with the formula CH2=CHCOOH. It is a carboxylic acid that contains a vinyl group. Acrylate esters are monomers that are widely used in the production of polymers, commonly known as acrylics. These polymers have a wide range of applications due to their diverse properties.

The polymerization of acrylate monomers typically occurs through free radical polymerization. The resulting polymers, polyacrylates, exhibit properties such as transparency, flexibility, and resistance to weathering and chemicals, depending on the specific acrylate ester used. Common acrylate esters include methyl acrylate, ethyl acrylate, butyl acrylate, and 2-ethylhexyl acrylate, each contributing different characteristics to the final polymer.

Acrylate-based polymers are found in numerous everyday products. They are used in paints and coatings, adhesives, textiles, sealants, and plastics. For example, acrylic paints are known for their durability and vibrant colors, while acrylic adhesives are valued for their strong bonding capabilities. The versatility of acrylates allows for the tailoring of polymer properties to meet specific performance requirements across various industries. Safety considerations are important when handling acrylate monomers, as some can be irritants or sensitizers.
