Beschreibung
Octadecyl acrylate is a versatile monomer extensively utilized in synthesizing polymer materials. It presents as a colorless and viscoelastic liquid. Its wide-ranging applications encompass coatings, adhesives, sealants, and printing inks, making it an indispensable ingredient in the polymer industry. Notably, Octadecyl acrylate contributes to the production of polymers used in various medical applications and the manufacturing of polyurethane foams. It serves as a valuable model for studying polymerization reactions, offering insights into the properties of polymer materials. During the polymerization process, Octadecyl acrylate undergoes a crucial reaction. This reaction involves the formation of covalent bonds between the monomer molecules. Precisely, addition polymerization occurs, where a monomer molecule adds to a double bond between two other monomer molecules, establishing the covalent bonds that create the polymer material.
Verwenden
stearyl acrylate is generally found in combination with other chemicals, it acts as a film former to help maintain moisture in the skin.
Verwenden
Octadecyl Acrylate is a reagent used in the synthesis of comb-like polymers which are incorporated into waterborne latexes improving barrier properties.
Application
Octadecyl acrylate undergoes surface-initiated atom transfer radical polymerization (ATRP) to form poly(octadecyl acrylate). ODA can form copolymers with cinnamoyloxy ethyl methacrylate (CEMA).
Flammability and Explosibility
Non flammable
