Polyacrylate: meaning, definitions and examples
🧪
polyacrylate
[ ˌpɒliˈækrɪleɪt ]
chemical compound
Polyacrylate is a synthetic polymer made from the polymerization of acrylic acid and its derivatives. It is known for its ability to absorb large amounts of water and is commonly used in products such as diapers, absorbent pads, and in agriculture for water retention in soil.
Synonyms
acrylic polymer, superabsorbent polymer.
Examples of usage
- The diaper contains polyacrylate to absorb moisture.
- Polyacrylate is often used in superabsorbent materials.
- In agriculture, polyacrylate helps retain water in dry soil.
Etymology
The term 'polyacrylate' is derived from 'poly-', meaning many, and 'acrylate', which relates to acrylic acid. Acrylic acid itself was first discovered in the mid-19th century, with its polymerization leading to a variety of acrylate compounds. The modern production of polyacrylate began in the 20th century, particularly after World War II, when synthetic polymers became more widely used in various industries. Polyacrylate's unique properties, especially its high absorbency, have made it a valuable material in medical, agricultural, and household applications. As research on polymers advanced, polyacrylate has been optimized for use in numerous commercial products, reflecting the ongoing innovation in materials science.
