The invention relates to (hydroxy)phosphinylalkyl acrylate, (hydroxy)phosphinylalkyl methacrylate (dihydroxy)phosphinylalkyl acrylate, methacrylate or ethacrylate or an alkali metal, alkaline earth metal or ammonium salt thereof.
In another aspect, the invention relates to a polymeric composition which comprises the reaction product of:
(a) between 0.5 and 100 percent by weight of a (hydroxy)phosphinylalkyl acrylate, (hydroxy)-phosphinylalkyl methacrylate, (dihydroxy)phosphinylalkyl acrylate, methacrylate or ethacrylate or an alkali metal, alkaline earth metal or ammonium salt thereof; and
(b) between 0 and 99.5 weight percent of a compound containing a polymerizable 1,2-ethylenically unsaturated moiety.
The polymeric compositions of this invention are prepared by methods well known in the art, such as solution polymerization, dispersion polymerization, emulsion polymerization, bulk polymerization and heterogeneous polymerization. These polymeric compositions have good adherence to many metals and enhanced anticorrosive properties.
