Abstract
A variety of phosphonylated heterochain polymers are disclosed, including, most preferably, phosphonylated polymethyl methacrylate. For each polymeric composition the phosphorous atom of a phosphorous-containing functional group is covalently bonded to a carbon atom of the polymeric chain. The phosphorous atoms are present in an amount of at least about 0.1 percent by weight in each polymeric composition.
Claims4
A randomly phosphonylated polyalkylene oxide polymer comprising phosphorous-containing functional groups, wherein the phosphorous atom of each of the functional groups is covalently bonded to a carbon atom of the polyalkylene oxide polymer and wherein the phosphorous atoms comprise at least about 0.1 percent by weight of the total polymer weight.
