Vinylphosphonic acid is a chemical compound with the molecular formula C2H3PO3. It belongs to the class of phosphonic acids, which are compounds containing a phosphorus atom bonded to three oxygen atoms and a carbon atom.
features：
The presence of the vinyl group makes vinylphosphonic acid reactive in polymerization reactions. It can participate in polymerization processes to incorporate phosphonic acid groups into polymer chains.
Adhibition：
One of the primary applications of VPA is as an adhesion promoter. It is used in coatings, adhesives, and sealants to enhance the adhesion of the material to various substrates. The phosphonic acid functionality interacts with the surface of the substrate, improving the bonding between the material and the substrate.
