Abstract

Disclosed are graft copolymers, compositions including graft copolymers, intermediate materials, and related methods, where the graft copolymer includes a first polymer component including a 1,1-disubstituted-1-alkene compound (preferably a methylene malonate compound) and is grafted to a second component. The resulting graft copolymer may be hydrophilic or water soluble. The second component preferably is a hydrophilic component.
