metanooltriglütseriid

Metanooltriglütseriid, also known as trimethylolpropane trimethacrylate (TMPTMA), is a crosslinking agent used in polymer chemistry. It is an ester derived from trimethylolpropane and methacrylic acid. Its chemical structure features a central trimethylolpropane molecule with three methacrylate groups attached to its hydroxyl functions. This trifunctional nature allows it to form highly crosslinked networks when polymerized with other monomers, particularly acrylates and methacrylates.

TMPTMA is widely employed in the formulation of UV-curable coatings, inks, and adhesives. Its ability to rapidly polymerize under ultraviolet light makes it suitable for high-speed manufacturing processes. The crosslinked polymers formed by TMPTMA exhibit excellent hardness, chemical resistance, and abrasion resistance. It is also used in dental composites and other applications where a durable and inert material is required. Due to its reactive double bonds, TMPTMA can undergo free radical polymerization. The presence of multiple methacrylate groups allows for efficient chain extension and crosslinking, leading to a rigid polymer matrix. It is typically a liquid at room temperature and is miscible with many common organic solvents and monomers.
