These include the vinyl addition polymers derived from common monomers like methyl methacrylate [9], acrylonitrile [10-12], styrene [13],butadiene [14], 4-vinylpyridine [15],acrylamide [15],andtetrafluoro ethylene [16]. In addition, selective polymers like polyfvinyl alcohol) [17],poly(N-vinyl pyrrolidone) [18], polyfethylene glycol) (PEG) [19], and others [20] have also been used.
