Polüakrüüdid

Polüakrüüdid, also known as polyacrylates, are a group of synthetic polymers derived from acrylic acid and its derivatives. They are characterized by the presence of ester groups within their repeating units. These versatile materials are produced through polymerization processes, typically free-radical polymerization, of monomers like acrylic acid, methyl acrylate, ethyl acrylate, butyl acrylate, and 2-ethylhexyl acrylate.

The physical and chemical properties of polyacrylates can be widely varied depending on the specific monomer used, the molecular weight of the polymer, and the presence of cross-linking agents. Generally, they exhibit good flexibility, adhesion, and weather resistance. Many polyacrylates are transparent and colorless. They can range from viscous liquids to rigid solids.

Polüakrüüdid find extensive use across numerous industries. They are commonly employed as binders in paints, coatings, and adhesives due to their excellent film-forming capabilities and durability. In the textile industry, they are used as finishing agents to improve fabric properties. They also serve as thickeners in cosmetic and personal care products, such as lotions and shampoos. Furthermore, certain polyacrylates are utilized in water treatment as flocculants and dispersants, and in agriculture as soil conditioners. Their ability to absorb and retain water also leads to applications in superabsorbent polymers.
