What are the properties of vinylphosphonic acids (VPA) and vinylphosphonic acid dimethyl esters (VPADME)?

VPA and VPADME undergo radical polymerization at mild temperatures (75 120 degrees Celsius). They promote adhesion and dissolve readily. Due to their phosphorus content, the monomers have flame-retardant properties. The excellent hydrolytic stability ensures that the phosphonic acid unit stays bonded to the polymer backbone even in unfavorable reaction conditions.
